+# Viewer: Study Prefetcher & Stack Prefetch
+
+Prefetching the stack of images of the active viewport is enabled by default for
+cornerstone viewports via cornerstone tools's stack prefetch functionality.
+
+In order to have a more customizable alternative for prefetching, OHIF provides
+a built-in study prefetcher functionality which allows the user to set the order
+in which the display sets are prefetched, the granularity, the timeout and
+whether or not display a progress bar in the display set (close to the thumbnail
+image) in the study browser.
+
+You can customize these options via the viewer's configuration:
+
+```js
+window.config = {
+  /**
+   * OHIF's study prefetcher configuration.
+   *
+   * @param {boolean} enabled Whether to enable/disable OHIF's study prefetcher
+   * @param {('all'|'closest'|'downward'|'upward'|'topdown')} order Fetching order: all display sets, the closest ones, downward or top down fashion based on the currently selected display set
+   * @param {number} displaySetCount How much display sets should be prefetched at once (note: this attribute is ignored if order was set to 'all')
+   * @param {boolean} preventCache Prevent images to be cached in Cornerstone Tools's request pool manager
