+# Getting Started
+
+## Setup
+
+### Fork & Clone
+
+If you intend to contribute back changes, or if you would like to pull updates
+we make to the OHIF Viewer, then follow these steps:
+
+- [Fork][fork-a-repo] the [OHIF/Viewers][ohif-viewers-repo] repository
+- [Create a local clone][clone-a-repo] of your fork
+  - `git clone https://github.com/YOUR-USERNAME/Viewers`
+- Add OHIF/Viewers as a [remote repository][add-remote-repo] labled `upstream`
+  - Navigate to the cloned project's directory
+  - `git remote add upstream https://github.com/OHIF/Viewers.git`
+
+With this setup, you can now [sync your fork][sync-changes] to keep it
+up-to-date with the upstream (original) repository. This is called a "Triangular
+Workflow" and is common for Open Source projects. The GitHub blog has a [good
+graphic that illustrates this setup][triangular-workflow].
+
+### Private
+
+Alternatively, if you intend to use the OHIF Viewer as a starting point, and you
+aren't as concerned with syncing updates, then follow these steps:
+
+1. Navigate to the [OHIF/Viewers][ohif-viewers] repository
+2. Click `Clone or download`, and then `Download ZIP`
+3. Use the contents of the `.zip` file as a starting point for your viewer
+
+> NOTE: It is still possible to sync changes using this approach. However,
+> submitting pull requests for fixes and features are best done with the
+> separate, forked repository setup described in "Fork & Clone"
+
+## Developing
+
+### Requirements
+
+- [Node.js & NPM](https://nodejs.org/en/)
+- [Yarn](https://yarnpkg.com/en/)
+- Yarn workspaces should be enabled:
+  - `yarn config set workspaces-experimental true`
+
+### Kick the tires
+
+Navigate to the root of the project's directory in your terminal and run the
+following commands:
+
+```bash
+# Restore dependencies
+yarn install
+
+# Start local development server
+yarn run dev
+```
+
+You should see the following output:
+
+```bash
+@ohif/viewer: i ｢wds｣: Project is running at http://localhost:3000/
+@ohif/viewer: i ｢wds｣: webpack output is served from /
+@ohif/viewer: i ｢wds｣: Content not from webpack is served from D:\code\ohif\Viewers\platform\viewer
+@ohif/viewer: i ｢wds｣: 404s will fallback to /index.html
+
+# And a list of all generated files
+```

+
+### Building for Production
+
+> More comprehensive guides for building and publishing can be found in our
+> [deployment docs](./deployment/index.md)
+
+```bash
+# Build static assets to host a PWA
+yarn run build
+
+# Build packaged output (script-tag use)
+yarn run build:package
+```
+
+## 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.
+- If you see a 'Loading' message which never resolves, check your browser
+  JavaScript console inside the Developer Tools to identify any errors.
