+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+In the interest of fostering an open and welcoming environment, we as
+contributors and maintainers pledge to making participation in our project and
+our community a harassment-free experience for everyone, regardless of age, body
+size, disability, ethnicity, sex characteristics, gender identity and expression,
+level of experience, education, socio-economic status, nationality, personal
+appearance, race, religion, or sexual identity and orientation.
+
+## Our Standards
+
+Examples of behavior that contributes to creating a positive environment
+include:
+
+* Using welcoming and inclusive language
+* Being respectful of differing viewpoints and experiences
+* Gracefully accepting constructive criticism
+* Focusing on what is best for the community
+* Showing empathy towards other community members
+
+Examples of unacceptable behavior by participants include:
+
+* The use of sexualized language or imagery and unwelcome sexual attention or
+ advances
+* Trolling, insulting/derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or electronic
+ address, without explicit permission
+* Other conduct which could reasonably be considered inappropriate in a
+ professional setting
+
+## Our Responsibilities
+
+Project maintainers are responsible for clarifying the standards of acceptable
+behavior and are expected to take appropriate and fair corrective action in
+response to any instances of unacceptable behavior.
+
+Project maintainers have the right and responsibility to remove, edit, or
+reject comments, commits, code, wiki edits, issues, and other contributions
+that are not aligned to this Code of Conduct, or to ban temporarily or
+permanently any contributor for other behaviors that they deem inappropriate,
+threatening, offensive, or harmful.
+
+## Scope
+
+This Code of Conduct applies both within project spaces and in public spaces
+when an individual is representing the project or its community. Examples of
+representing a project or community include using an official project e-mail
+address, posting via an official social media account, or acting as an appointed
+representative at an online or offline event. Representation of a project may be
+further defined and clarified by project maintainers.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported by contacting the project team at danny.ri.brown+OHIFcoc@gmail.com. All
+complaints will be reviewed and investigated and will result in a response that
+is deemed necessary and appropriate to the circumstances. The project team is
+obligated to maintain confidentiality with regard to the reporter of an incident.
+Further details of specific enforcement policies may be posted separately.
+
+Project maintainers who do not follow or enforce the Code of Conduct in good
+faith may face temporary or permanent repercussions as determined by other
+members of the project's leadership.
+
+## Attribution
+
+This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.4,
+available at https://www.contributor-covenant.org/version/1/4/code-of-conduct.html

-# Extensions
-
-Extensions add new functionality to the viewer by registering one or more
-modules. They go one step further than configuration in that they allow us to
-inject custom React components, so long as they adhere to the module's
-interface. This can be something as simple as adding a new button to the
-toolbar, or as complex as a new viewport capable of rendering volumes in 3D.

-
-## Overview
-
-At a glance, an extension is a javascript object that has an `id` property, and
-one or more "module" methods. You can find an abbreviated extension below, or
-[view the source][example-ext-src] of our example extension.
-
-```js
-export default {
-    /**
-     * Only required property. Should be a unique value across all extensions.
-     */
-    id: 'example-extension',
-
-    /**
-     * Registers one or more named commands scoped to a context. Commands are
-     * the primary means for...
-     */
-    getCommandsModule() {
-        return {
-            defaultContext: 'VIEWER'
-            actions: { ... },
-            definitions: { ... }
-        }
-    },
-
-    /**
-     * Allows you to provide toolbar definitions that will be merged with any
-     * existing application toolbar configuration. Used to determine which
-     * buttons should be visible when, their order, what happens when they're
-     * clicked, etc.
-     */
-    getToolbarModule() {
-        return {
-            definitions: [ ... ],
-            defaultContext: 'ACTIVE_VIEWPORT::CORNERSTONE'
-        }
-    }
-
-    /**

-     */
-    getPanelModule: () => null,
-
-    /**
-     * Registers a ReactComponent that should be used to render data in a
-     * Viewport. The first registered viewport is our "default viewport". If
-     * more than one viewport is registered, we use `SopClassHandlers` to
-     * determine which viewport should be used.
-    */
-    getViewportModule: () => reactViewportComponent,
-
-    /** Provides a whitelist of SOPClassUIDs the viewport is capable of rendering.
-     *  Can modify default behavior for methods like `getDisplaySetFromSeries` */
-    getSopClassHandler: () => {
-        id: 'some-other-unique-id',
-        sopClassUids: [ ... ],
-        getDisplaySetFromSeries: (series, study, dicomWebClient, authorizationHeaders) => { ... }
-    },
-}
-```
-
-### Modules
-
-There are a few different module types. Each module type allows us to extend the
-viewer in a different way, and provides a consistent API for us to do so. You
-can find a full list of the different types of modules
-[`in ohif-core`][module-types]. Information on each type of module, it's API,
-and how we determine when/where it should be used is included below.
-
-> NOTE: Modifying the extensions/modules registered to the OHIF Viewer currently
-> requires us to import and pass extensions to the ExtensionManager in
-> `src/App.js`, then rebuild the application. Long-term, we intend to make it
-> possible to accomplish this without a build step.
-
-#### Commands
-
-The Commands Module allows us to register one or more commands scoped to
-specific contexts. Commands can be run by [hotkeys][#], [toolbar buttons][#],
-and any registered custom react component (like a [viewport][#] or [panel][#]).
-Here is a simple example commands module:
-
-```js
-{
-    getCommandsModule() {
-        return {
-            actions: {
-                speak: ({ viewports, words }) => {
-                    console.log(viewports, words);
-                },
-            },
-            definitions: {
-                rotateViewportCW: {
-                    commandFn: actions.rotateViewport,
-                    storeContexts: ['viewports'],
-                    options: { rotation: 90 }
-                },
-                rotateViewportCCW: {
-                    commandFn: actions.rotateViewport,
-                    storeContexts: ['viewports'],
-                    options: { rotation: -90 },
-                    context: 'ACTIVE_VIEWER::CORNERSTONE'
-                },
-            },
-            defaultContext: 'VIEWER'
-        }
-    }
-}
-```
-
-#### Viewport
-
-An extension can register a Viewport Module by providing a `getViewportModule()`
-method that returns a React Component. The React component will receive the
-following props:
-
-```js
-children: PropTypes.arrayOf(PropTypes.element)
-studies: PropTypes.object,
-displaySet: PropTypes.object,
-viewportData: PropTypes.object, // { studies, displaySet }
-viewportIndex: PropTypes.number,
-children: PropTypes.node,
-customProps: PropTypes.object
-```
-
-Viewport components are managed by the `LayoutManager`. Which Viewport component
-is used depends on:
-
-- The Layout Configuration
-- Registered SopClassHandlers
-- The SopClassUID for visible/selected datasets
-
-![Cornerstone Viewport](../assets/img/extensions-viewport.png)
-
-<center><i>An example of three Viewports</i></center>
-
-For a complete example implementation,
-[check out the OHIFCornerstoneViewport](https://github.com/OHIF/Viewers/blob/master/extensions/cornerstone/src/OHIFCornerstoneViewport.js).
-
-#### Toolbar
-
-An extension can register a Toolbar Module by providing a `getToolbarModule()`
-method that returns a React Component. The component does not receive any props.
-If you want to modify or react to state, you will need to connect to the redux
-store.
-
-![Toolbar Extension](../assets/img/extensions-toolbar.gif)
-
-<center><i>A toolbar extension example</i></center>
-
-Toolbar components are rendered in the `ToolbarRow` component.

-For a complete example implementation,
-[check out the OHIFCornerstoneViewport's Toolbar Module](https://github.com/OHIF/Viewers/blob/master/extensions/cornerstone/src/toolbarModule.js).

-
-### Registering Extensions
-
-Extensions are registered for the application at startup. The
-`ExtensionManager`, exposed by `ohif-core`, registers a list of extensions with
-our application's store. Each module provided by the extension becomes available
-via `state.plugins.availablePlugins`, and consists of three parts: id, type
-([PLUGIN_TYPE](https://github.com/OHIF/ohif-core/blob/43c08a29eff3fb646a0e83a03a236ddd84f4a6e8/src/plugins.js#L1-L6)),
-and the return value of the module method.
-
-In a future version, we will likely expose a way to provide the extensions you
-would like included at startup.
-
-_app.js_
-
-```js
-import { createStore, combineReducers } from 'redux';
-import OHIF from '@ohif/core';
-import OHIFCornerstoneExtension from 'ohif-cornerstone-extension';
-
-const combined = combineReducers(OHIF.redux.reducers);
-const store = createStore(combined);
-const extensions = [new OHIFCornerstoneExtension()];
-
-// Dispatches the `addPlugin` action to the store
-// Adding extension modules to `state.plugins.availablePlugins`
-ExtensionManager.registerExtensions(store, extensions);
-```
-
-## OHIF Maintained Extensions
-
-A small number of powerful extensions for popular use cases are maintained by
-OHIF. They're co-located in the
-[`OHIF/Viewers`](https://github.com/OHIF/Viewers) repository, in the top level
-[`extensions/`](https://github.com/OHIF/Viewers/tree/master/extensions)

+# Continous Integration (CI)
+
+This repository uses `CircleCI` and `Netlify` for continous integration.
+
+## Deploy Previews
+
+[Netlify Deploy previews][deploy-previews] are generated for every pull request.
+They allow pull request authors and reviewers to "Preview" the OHIF Viewer as if
+the changes had been merged.
+
+Deploy previews can be configured by modifying the `netlify.toml` file in the
+root of the repository. Some additional scripts/assets for netlify are included
+in the root `.netlify` directory.
+
+## Workflows
+
+[CircleCI Workflows][circleci-workflows] are a set of rules for defining a
+collection of jobs and their run order. They are self-documenting and their
+configuration can be found in our CircleCI configuration file:
+`.circleci/config.yml`.
+
+### Workflow: PR_CHECKS
+
+The PR_CHECKS workflow (Pull Request Checks) runs our automated unit and
+end-to-end tests for every code check-in. These tests must all pass before code
+can be merged to our `master` branch.

+
+### Workflow: PR_OPTIONAL_DOCKER_PUBLISH
+
+The PR_OPTIONAL_DOCKER_PUBLISH workflow allows for "manual approval" to publish

+> merge the changes to a short-lived `feature/` branch on `upstream`
+
+### Workflow: DEPLOY
+
+The DEPLOY workflow deploys the OHIF Viewer when changes are merged to master.
+It uses the Netlify CLI to deploy assets created as part of the repository's PWA
+Build process (`yarn run build`). The workflow allows for "Manual Approval" to
+promote the build to `STAGING` and `PRODUCTION` environments.

-different topics may be more pertinent than others. At a minimum, reading "The
-Essentials" and the deployment recipes should be a good starting point.

 ## Troubleshooting
 
 - If you receive a _"No Studies Found"_ message and do not see your studies, try
   changing the Study Date filters to a wider range.

+## Overview
+
+We use extensions to help us isolate and package groups of related features.
+Extensions provide functionality, ui components, and new behaviors. Ideally,
+they're built in a way that allows them to extend entirely different
+implementations of the `@ohif/viewer` project.

+
+The `@ohif/viewer`'s application level configuration gives us the ability to add
+and configure extensions. When the application starts, extensions are registered
+with the `ExtensionManager`. Different portions of the `@ohif/viewer` project
+will use registered extensions to influence application behavior.
+
+Extensions allow us to:
+
+- Wrap and integrate functionality of 3rd party dependencies in a reusable way
+- Change how application data is mapped and transformed
+- Display a consistent/cohesive UI
+- Inject custom components to override built-in components
+
+Practical examples of extensions include:
+
+- A set of segmentation tools that build on top of the `cornerstone` viewport
+- Showing ML/AI report summaries for the selected study/series/image
+- Support for parsing DICOM structured reports and displaying them in a user
+  friendly way
+- [See our maintained extensions for more examples of what's possible](#maintained-extensions)
+
+## Concepts
+
+### Extension Skeleton
+
+An extension is a plain JavaScript object that has an `id` property, and one or
+more [modules](#modules) and/or [lifecycle hooks](#lifecycle-hooks).
+
+```js
+// prettier-ignore
+export default {
+  /**
+   * Only required property. Should be a unique value across all extensions.
+   */
+  id: 'example-extension',
+
+  // Lifecyle
+  preRegistration() { /* */ },
+  // Modules
+  getCommandsModule() { /* */ },
+  getToolbarModule() { /* */ },
+  getPanelModule() { /* */ },
+  getSopClassHandler() { /* */ },
+  getViewportModule() { /* */ },
+}
+```
+
+### Registering an Extension
+
+There are two different ways to register and configure extensions: At
+[runtime](#runtime-extensions) and at [build time](#bundled-extensions).
+
+You can leverage one or both strategies. Which one(s) you choose depend on your
+application's requirements. Each [module](#modules) defined by the extension
+becomes available to the core application via the `ExtensionManager`.
+
+#### Registering at Runtime
+
+The `@ohif/viewer` uses a [configuration file](#) at startup. The schema for
+that file includes an `Extensions` key that supports an array of extensions to
+register.
+
+```js
+// prettier-ignore
+const config = {
+  extensions: [
+    MyFirstExtension,
+    [
+      MySecondExtension,
+      { /* MySecondExtensions Configuration */ },
+    ],
+  ];
+}
+```
+
+#### Registering at Build Time
+
+The `@ohif/viewer` works best when built as a "Progressive Web Application"
+(PWA). If you know the extensions your application will need, you can specify
+them at "build time" to leverage advantages afforded to us by modern tooling:
+
+- Code Splitting (dynamic imports)
+- Tree Shaking
+- Dependency deduplication
+
+You can update the list of bundled extensions by:
+
+1. Having your `@ohif/viewer` project depend on the extension
+2. Importing and adding it to the list of extensions in the
+   `<repo-root>/platform/src/index.js` entrypoint.
+
+### Lifecycle Hooks
+
+Currently, there is only a single lifecycle hook for extensions:
+[`preRegistration`](./lifecycle/pre-registration.md)
+
+If an extension defines the [`preRegistration`](./lifecycle/pre-registration.md)
+lifecycle hook, it is called before any modules are registered in the
+`ExtensionManager`. It's most commonly used to wire up extensions to
+[services](./../services/index.md) and [commands](./modules/commands.md), and to
+bootstrap 3rd party libraries.
+
+### Modules
+
+Modules are the meat of extensions. They provide "definitions", components, and
+filtering/mapping logic that are then made available by various managers and
+services.
+
+Each module type has a special purpose, and is consumed by our viewer
+differently.
+
+| Type                                              | Description                                                      | Examples                                          |
+| ------------------------------------------------- | ---------------------------------------------------------------- | ------------------------------------------------- |
+| [Commands](./modules/commands.md)                 | Adds named commands, scoped to a context, to the CommandsManager | `setToolActive()`, `nextSeries()`                 |
+| [Panel](./modules/panel.md)                       | Adds left or right hand side panels                              | `<ThumbnailList />`, `<MeasurementsTable />`      |
+| [SOPClassHandler](./modules/sop-class-handler.md) | Determines how retrieved study data is split into "DisplaySets"  | `getDisplaySetFromSeries()`                       |
+| [Toolbar](./modules/toolbar.md)                   | Adds buttons or custom components to the toolbar                 | Toolbar button, nested buttons, custom            |
+| [Viewport](./modules/viewport.md)                 | Adds a component responsible for rendering a "DisplaySet"        | `<CornerstoneViewport />`, `<DicomPdfViewport />` |
+
+<figure style="text-align: center; font-style: italic;">Tbl. Module types with abridged descriptions and examples. Each module links to a dedicated documentation page.</figure>
+
+### Contexts
+
+The `@ohif/viewer` tracks "active contexts" that extensions can use to scope
+their functionality. Some example contexts being:
+
+- Route: `ROUTE:VIEWER`, `ROUTE:STUDY_LIST`
+- Active Viewport: `ACTIVE_VIEWPORT:CORNERSTONE`, `ACTIVE_VIEWPORT:VTK`
+
+An extension module can use these to say "Only show this Toolbar Button if the
+active viewport is a Cornerstone viewport." This helps us use the appropriate UI
+and behaviors depending on the current contexts.
+
+For example, if we have hotkey that "rotates the active viewport", each Viewport
+module that supports this behavior can add a command with the same name, scoped
+to the appropriate context. When the `command` is fired, the "active contexts"
+are used to determine the appropriate implementation of the rotate behavior.
+
+## Consuming Extensions
+
+We consume extensions, via the `ExtensionManager`, in our `@ohif/viewer`
+project.
+
+```js
+const extensionManager = new ExtensionManager({
+  commandsManager,
+  servicesManager,
+});
+
+// prettier-ignore
+extensionManager.registerExtensions([ /** **/ ]);
+```
+
+The `@ohif/viewer` project handles data fetching, basic routing, wires up UI
+services, and is the home to the more bespoke application logic that doesn't
+make as much sense to make reusable.
+
+Long-term, replacing the `@ohif/viewer` application and consuming extensions
+(and the `ExtensionManager`) in your own project is the ideal path for
+applications requiring a high degree of customization that can't be achieved
+with current theming, configuration, extension, and services support.
+
+If you're not sure how to achieve your goals with the extensibility available
+today, create a GitHub issue!
+
+### `ExtensionManager`
+
+The `ExtensionManager` is a class made available to us via the `@ohif/core`
+project (platform/core). Our application instantiates a single instance of it,
+and provides a `ServicesManager` and `CommandsManager`.
+
+```js
+const commandsManager = new CommandsManager();
+const servicesManager = new ServicesManager();
+const extensionManager = new ExtensionManager({
+  commandsManager,
+  servicesManager,
+});
+```
+
+The `ExtensionManager` only has a few public members:
+
+- `registerExtension` - Registers a single extension
+- `registerExtensions` - Registers an array of extensions
+- `modules` - An object containing registered extensions by `MODULE_TYPE`
+
+During registration, lifecycle hooks and modules have access to
+`ExtensionManager`'s `ServicesManager` and `CommandsManager`.
+
+Our `@ohif/viewer` uses the `modules` member to access registered extensions at
+appropriate places in our application.
+
+## Maintained Extensions
+
+A small number of powerful extensions for popular use cases are maintained by
+OHIF. They're co-located in the [`OHIF/Viewers`][viewers-repo] repository, in
+the top level [`extensions/`][ext-source] directory.

+# Lifecylce Hook: preRegistration
+
+If an extension defines the `preRegistration` lifecycle hook, it is called

+  - [Public API](#public-api)
+  - [Contexts](#contexts)
+
+## Overview
+
+An extension can register a Commands Module by defining a `getCommandsModule`
+method. The Commands Module allows us to register one or more commands scoped to
+specific [contexts](./../index.md#contexts). Commands have several unique
+characteristics that make them tremendously powerful:
+
+- Multiple implementations for the same command can be defined
+- Only the correct command's implementation will be run, dependent on the
+  application's "context"
+- Commands can be called from extensions, modules, and the consuming application
+
+Here is a simple example commands module:
+
+```js
+export default {
+  id: 'example-commands-module',
+
+  /**
+   * @param {object} params
+   * @param {ServicesManager} params.servicesManager
+   * @param {CommandsManager} params.commandsManager
+   */
+  getCommandsModule({ servicesManager, commandsManager }) {
+    return {
+      definitions: {
+        sayHello: {
+          commandFn: ({ words }) => {
+            console.log(words);
+          },
+          options: { words: 'Hello!' },
+        },
+      },
+      defaultContext: 'VIEWER',
+    };
+  },
+};
+```
+
+Each definition returned by the Commands Module is registered to the
+`ExtensionManager`'s `CommandsManager`.
+
+## Command Definitions
+
+The command definition consists of a named command (`myCommandName` below) and a
+`commandFn`. The command name is used to call the command, and the `commandFn`
+is the "command" that is actioned.
+
+```js
+myCommandName: {
+	commandFn: ({ viewports, other, options }) => { },
+	storeContexts: ['viewports'],
+	options: { words: 'Just kidding! Goodbye!' },
+	context: 'ACTIVE_VIEWPORT::CORNERSTONE',
+}
+```
+
+| Property        | Type               | Description                                                                                                                             |
+| --------------- | ------------------ | --------------------------------------------------------------------------------------------------------------------------------------- |
+| `commandFn`     | func               | The function to call when command is run. Receives `options` and `storeContexts`.                                                       |
+| `storeContexts` | string[]           | (optional) Expected state objects to be passed in as props. Located using `getAppState` fn defined at `CommandsManager`'s instatiation. |
+| `options`       | object             | (optional) Arguments to pass at the time of calling to the `commandFn`                                                                  |
+| `context`       | string[] or string | (optional) Overrides the `defaultContext`. Let's us know if command is currently "available" to be run.                                 |
+
+## Command Behavior
+
+**I have many similar commands. How can I share their `commandFn` and make it
+reusable?**
+
+This is where `storeContexts` and `options` come in. We use these in our
+`setToolActive` command. `storeContexts` helps us identify our `activeViewport`,
+and `options` allow us to pass in the name of a tool we would like to set as
+active.
+
+**If there are multiple valid commands for the application's active contexts**
+
+- What happens: all commands are run
+- When to use: A `clearData` command that cleans up state for multiple
+  extensions
+
+**If no commands are valid for the application's active contexts**
+
+- What happens: a warning is printed to the console
+- When to use: a `hotkey` (like "invert") that doesn't make sense for the
+  current viewport (PDF or HTML)
+
+## `CommandsManager`
+
+The `CommandsManager` is a class defined in the `@ohif/core` project. A single
+instance of it should be defined in the consuming application, and it should be
+used when constructing the `ExtensionManager`.
+
+### Instantiating
+
+When we instantiate the `CommandsManager`, we need to pass it two methods:
+
+- `getAppState` - Should return the application's state when called
+- `getActiveContexts` - Should return the application's active contexts when
+  called
+
+These methods are used internally to help determine which commands are currently
+valid, and how to provide them with any state they may need at the time they are
+called.
+
+```js
+const commandsManager = new CommandsManager({
+  getAppState,
+  getActiveContexts,
+});
+```
+
+### Public API
+
+If you would like to run a command in the consuming app or an extension, you can
+use one of the following methods:
+
+```js
+// Returns all commands for a given context
+commandsManager.getContext('string');
+
+// Attempts to run a command
+commandsManager.runCommand('speak', { command: 'hello' });
+
+// Run command, but override the active contexts
+commandsManager.runCommand('speak', { command: 'hello' }, ['VIEWER']);
+```
+
+The `ExtensionManager` handles registering commands and creating contexts, so
+most consumer's won't need these methods. If you find yourself using these, ask
+yourself "why can't I register these commands via an extension?"
+
+```js
+// Used by the `ExtensionManager` to register new commands
+commandsManager.registerCommand('context', 'name', commandDefinition);
+
+// Creates a new context; clears the context if it already exists
+commandsManager.createContext('string');
+```
+
+### Contexts
+
+It is up to the consuming application to define what contexts are possible, and
+which ones are currently active. As extensions depend heavily on these, we will
+likely publish guidance around creating contexts, and ways to override extension
+defined contexts in the near future. If you would like to discuss potential
+changes to how contexts work, please don't hesistate to createa new GitHub
+issue.

+# Module: SOP Class Handler
+
+An extension can register a SOP Class Handler Module by defining a
+`getSopClassHandlerModule` method. The SOP Class Handler is a bit different from
+the other modules, as it doesn't provide a `1:1` schema for UI or provide it's
+own components. It instead defines:
+
+- `sopClassUids`: an array of string SOP Class UIDs that the
+  `getDisplaySetFromSeries` method should be applied to.
+- `getDisplaySetFromSeries`: a method that maps series and study metadata to a
+  display set
+
+A `displaySet` has the following shape:
+
+```js
+return {
+  plugin: 'html',
+  modality: 'SR',
+  displaySetInstanceUid: 0,
+  wadoRoot: study.getData().wadoRoot,
+  wadoUri: instance.getData().wadouri,
+  sopInstanceUid: instance.getSOPInstanceUID(),
+  seriesInstanceUid: series.getSeriesInstanceUID(),
+  studyInstanceUid: study.getStudyInstanceUID(),
+  authorizationHeaders,
+};
+```
+
+Where the `plugin` key is used to influence the default `ViewportComponent` for
+rendering the `displaySet`. Additional properties are passed to the
+`ViewportComponent` and used by the default `StudyBrowser` to render
+"thumbnails" for each `displaySet`
+
+## Example SOP Class Handler Module

+## `@ohif/viewer` usage
+
+We use the `sopClassHandlerModule`s in three different places:
+
+- `ViewerLocalFileData.js`
+- `ViewerRetrieveStudyData.js`
+- `StandaloneRouting.js`
+
+Each time, it is used to map study and series data to `displaySets`. It does
+this by working alongside the `StudyMetadataManager` in `@ohif/core`. That
+manager has the method `createDisplaySets` that takes an array of
+`sopClassHandlerModules`.

+| `type`           | Used to determine the button's component and behavior             | `"setToolActive"`, `"command"`            |

+| `commandOptions` | (optional) Options to pass the target `commandName`               | \*                                        |

+Where a button with a `type` of `setToolActive` has an "active" styling applied
+when clicked; removing the active styling from all other buttons.
+
+## Nested Toolbar Menus
+
+You can indicate that buttons should be grouped and nested in a submenu by
+including `buttons` property in a definition:
+
+```js
+{
+  id: 'More',
+  label: 'More',
+  icon: 'ellipse-circle',
+  buttons: [
+    {
+      id: 'cstInvert',
+      label: 'Invert',
+      icon: 'circle',
+      type: 'command',
+      commandName: 'invertViewport',
+    },
+  ],
+},
+```
+
+![Toolbar Extension](../../assets/img/extensions-toolbar-nested.gif)
+
+<center><i>Example toolbar button demonstrating nested buttons.</i></center>
+
+## Custom Components
+
+The Toolbar Modules supports rendering custom components in place of the
+application's default. In place of the `type`, `commandName`, and
+`commandOptions` properties, we instead specify a `CustomComponent`.
+
+```js
+{
+  id: 'Custom',
+  label: 'Custom',
+  icon: 'custom-icon',
+  CustomComponent: CustomToolbarComponent,
+}
+
+```
+
+The `CustomComponent` components will receive the following props:
+
+```html
+<CustomComponent
+  parentContext="{parentContext}"
+  toolbarClickCallback="{_handleToolbarButtonClick.bind(this)}"
+  button="{button}"
+  key="{button.id}"
+  activeButtons="{activeButtonsIds}"
+  isActive="{isActive}"
+/>
+```
+
+| Property               | Type     | Description                     |
+| ---------------------- | -------- | ------------------------------- |
+| `activeButtons`        | string[] | list of active buttons          |
+| `button`               | object   | its own definition object       |
+| `key`                  | string   | React key prop                  |
+| `isActive`             | boolean  | If current button is active     |
+| `parentContext`        | ?        | The parent component's context? |
+| `toolbarClickCallback` | func     | Callback method for clicks      |

+# Module: Viewport
+
+An extension can register a Viewport Module by defining a `getViewportModule`
+method that returns a React component. Currently, we use viewport components to
+add support for:
+
+- 2D Medical Image Viewing (cornerstone ext.)
+- Structured Reports as HTML (dicom html ext.)
+- Encapsulated PDFs as PDFs (dicom pdf ext.)
+- Whole Slide Microscopy Viewing (whole slide ext.)
+- etc.
+
+The general pattern is, the [`sopClassHandlerModule`](#) helps us determine
+which Viewport Component a set of `sopClassUIDs` should default to. The Viewport
+Component receives props containing a display set it should know how to render.
+
+## Viewport Component Props
+
+Each `ViewportComponent` will receive the following props:
+
+```html
+<viewportComponent
+  viewportData="{viewportData}"
+  viewportIndex="{viewportIndex}"
+  children="{[children]}"
+/>
+```
+
+| Property        | Type            | Description                       |
+| --------------- | --------------- | --------------------------------- |
+| `children`      | React.element[] |                                   |
+| `viewportData`  | object          | `viewportSpecificData` (probably) |
+| `viewportIndex` | number          |                                   |
+
+### `@ohif/viewer`
+
+Viewport components are managed by the `ViewportGrid` Component. Which Viewport
+component is used depends on:
+
+- The Layout Configuration
+- Registered SopClassHandlers
+- The SopClassUID for visible/selected datasets

+## Issue Triage
+
+[GitHub issues][gh-issues] are the best way to provide feedback, ask questions,
+and suggest changes to the OHIF Viewer's core team. Community issues generally
+fall into one of three categories, and are marked with a `triage` label when
+created.
+
+| Issue Template Name    | Description                                                                              |

+| Community: Question ❓ | Seek clarification or assistance relevant to the repository.                             |
+
+_table 1. issue template names and descriptions_
+
+Issues that require `triage` are akin to support tickets. As this is often our
+first contact with would-be adopters and contributors, it's important that we
+strive for timely responses and satisfactory resolutions. We attempt to
+accomplish this by:
+
+1. Responding to issues requiring `triage` at least once a week
+2. Create new "official issues" from "community issues"
+3. Provide clear guidance and next steps (when applicable)
+4. Regularly clean up old (stale) issues

+### Backlogged Issues
+
+Community issues serve as vehicles of discussion that lead us to "backlogged
+issues". Backlogged issues are the distilled and actionable information
+extracted from community issues. They contain the scope and requirements
+necessary for hand-off to a core-team (or community) contributor ^\_^

+
+If a [GitHub issue][gh-issues] has a `bug`, `story`, or `task` label; it's on
+our backlog. If an issue is on our backlog, it means we are, at the very least,
+committed to reviewing any community drafted Pull Requests to complete the
+issue. If you're interested in seeing an issue completed but don't know where to
+start, please don't hesitate to leave a comment!
+
+While we don't yet have a long-term or quarterly road map, we do regularly add
+items to our ["Active Development" GitHub Project Board][gh-board]. Items on
+this project board are either in active development by Core Team members, or
+queued up for development as in-progress items are completed.

+
+We rely on GitHub Checks and integrations with third party services to evaluate
+changes in code quality and test coverage. Tests must pass and User cases must
+be present (when applicable) before a PR can be merged to master, and code
+quality and test coverage must not changed by a significant margin. For some
+repositories, visual screenshot-based tests are also included, and video
+recordings of end-to-end tests are stored for later review.
+
+[You can read more about our continous integration efforts here](/development/continous-integration.md)
+
+## Releases
+
+Releases are made automatically based on the type of commits which have been
+merged (major.minor.patch). Releases are automatically pushed to NPM. Release
+notes are automatically generated. Users can subscribe to GitHub and NPM
+releases.
+
+We host development, staging, and production environments for the Progressive
+Web Application version of the OHIF Viewer. [Development][ohif-dev] always
+reflects the latest changes on our master branch. [Staging][ohif-stage] is used
+to regression test a release before a bi-weekly deploy to our [Production
+environment][ohif-prod].
+
+Important announcements are made on GitHub, tagged as Announcement, and pinned
+so that they remain at the top of the Issue page.
+
+The Core team occasionally performs full manual testing to begin the process of
+releasing a Stable version. Once testing is complete, the known issues are
+addressed and a Stable version is released.

+  </a>
+  <div><i>Diagram showing relationship between React Context and UI Service</i></div>
+</div>
+
+## Example
+
+The simplest service return a new object that has a `name` property, and
+methods/properties that give the service its functionality. The "Factory
+Function" that creates the service is provided with the implementation (this is
+slightly different for UI Services).
+
+```js
+const _speak = () => {
+  console.warn('Speak is not implemented');
+};
+
+/**
+ * Factory function to create `HelloWorldService`
+ *
+ * @param {object} implementation
+ * @param {function} implementation.speak - Speak's implementation
+ * @returns HelloWorldService
+ */
+export default function createHelloWorldService({ speak }) {
+  return {
+    name: 'HelloWorldService',
+    speak: speak || _speak,
+  };
+}
+```
+
+A service, once created, can be registered with the `ServicesManager` to make it
+accessible to extensions. Similarly, the application code can access named
+services from the `ServicesManager`.
+
+```js
+// In the application
+const speak = () => {
+  window.alert('HELLO WORLD');
+};
+const HelloWorldService = createHelloWorldService({ speak });
+const servicesManager = new ServicesManager();
+
+servicesManager.registerService(HelloWorldService);
+
+// In an extension
+const { HelloWorldService } = servicesManager.services;
+
+if (HelloWorldService) {
+  HelloWorldService.speak();
+}
+```

+  - [UI Services](#ui-services)
+- [Related Patterns](#related-patterns)
+
+## Overview
+
+Services are a beefier version of [commands][commands]. They provide a set of
+operations, often tied to some shared state, and are made available to
+extensions via the `ServicesManager`. Services are particularly well suited to
+address [cross-cutting concerns][cross-cutting-concerns].
+
+Each service should be:
+
+- self-contained
+- able to fail and/or be removed without breaking the application
+- completely interchangeable with another module implementing the same interface
+
+## Kinds of Services
+
+Depending on the kind of service, we follow slightly different conventions. For
+example, a UI service often receives its implementation from a React Context
+Provider. You can read more about the different kinds of services and what makes
+them different below:
+
+### Services (default)
+
+Services are a work in progress. As we are still in the progress of creating a
+non-ui maintained service, this usage may change.
+
+[You can read more about default services: here](./default/index.md)
+
+### UI Services
+
+A typical web application will have components and state for common UI like
+modals, notifications, dialogs, etc. A UI service makes it possible to leverage
+these components from an extension.
+
+We maintain the following UI Services:
+
+- [UIDialogService](./ui/ui-dialog-service.md)
+- [UIModalService](./ui/ui-modal-service.md)
+- [UINotificationService](./ui/ui-notification-service.md)
+
+You can read more about a specific service by selecting it in the above list,
+and more about [UI services in general: here](./ui/index.md)
+
+## Related Patterns
+
+Services are "concern-specific" code modules that can be consumed across layers.
+We try to minimize the coupling they introduce by authoring services that are

+
+## Overview
+
+A typical web application will have components and state for common UI like
+modals, notifications, dialogs, etc. A UI service makes it possible to leverage
+these components from an extension.
+
+<div style="text-align: center;">
+  <a href="/assets/img/ui-services.png">
+    <img src="/assets/img/ui-services.png" alt="UI Services Diagram" style="margin: 0 auto; max-width: 500px;" />
+  </a>
+  <div><i>Diagram showing relationship between React Context and UI Service</i></div>
+</div>
+
+In `@ohif/core`, we have a collection of service factories. We select one we
+would like our application to support, create an instance of it, and pass that
+instance to our `ServicesManager` AND to a React component (in this example,
+`ModalContext`'s provider).
+
+The `ModalContext`'s provider:
+
+- Exposes context values
+- Exposes methods that leverage `useCallback` hooks
+- Sets the service's implementation in a `useEffect` hook
+
+The `ServicesManager` is:
+
+- Passed to the `ExtensionManager`
+- The `ExtensionManager` makes the `ServicesManager` available to:
+  - All of it's lifecycle hooks (`preRegistration`)
+  - Each "getModuleFunction" (`getToolbarModule`, `getPanelModule`, etc.)
+
+## Example
+
+That's all fine and good, but it's still a little too abstract. What does this
+translate to in practice?
+
+```js
+// In the application
+import UINotificationService from '@ohif/core';
+const servicesManager = new ServicesManager();
+
+servicesManager.registerService(UINotificationService);
+
+// UI Service Provider
+useEffect(() => {
+  if (service) {
+    service.setServiceImplementation({ hide, show });
+  }
+}, [service, hide, show]);
+
+// In an extension
+const { UINotificationService } = servicesManager.services;
+
+if (UINotificationService) {
+  UINotificationService.show('Hello from the other side 👋');
+}
+```
+

+  </a>
+  <div><i>GIF showing successful call of UINotificationService from an extension.</i></div>
+</div>
+
+## Tips & Tricks
+
+It's important to remember that all we're doing is making it possible to control
+bits of the application's UI from an extension. Here are a few non-obvious
+takeaways worth mentioning:
+
+- Your application code should continue to use React context
+  (consumers/providers) as it normally would
+- You can substitute our "out of the box" UI implementations with your own
+- You can create and register your own UI services
+- You can choose not to register a service or provide a service implementation
+- In extensions, you can provide fallback/alternative behavior if an expected
+  service is not registered
+  - No `UIModalService`? Use the `UINotificationService` to notify users.
+- While we don't have an examples of this, you can technically register a
+  service in an extension and expose it to the core application
+
+> Note: These are recommended patterns, not hard and fast rules. Following them
+> will help reduce confusion and interoperability with the larger OHIF
+> community, but they're not silver bullets. Please speak up, create an issue,
+> if you would like to discuss new services or improvements to this pattern.
+
+## Maintained Services
+
+Our `@ohif/viewer` project is an example of how to glue together the different
+parts and pieces of the OHIF Platform to create a polished and powerful product.
+To accomplish that, we maintain several UI Services that you can use in your own
+project, or provide alternative implementations for:

+# UI Notification Service
+
+Notifications can be annoying and disruptive. They can also deliver timely
+helpful information, or expedite the user's workflow. Here is some high level
+guidance on when and how to use them:
+
+- Notifications should be non-interfering (timely, relevant, important)
+- We should only show small/brief notifications
+- Notifications should be contextual to current behavior/actions
+- Notifications can serve warnings (acting as a confirmation)
