+<h2>ECLIPSE THEIA - EDITOR-PREVIEW EXTENSION</h2>
+
+<hr />
+
+</div>
+
+## Description
+
+The `@theia/editor-preview` extension contributes the preview editor which  supports the same functionality as a regular editor widget with the exception:
+
+- if a preview editor has not "transitioned to a permanent editor" at the time an additional request to
+preview a file is received, instead of opening a new editor, it will display the contents of the
+newly requested file.
+
+Events that will transition the preview to a permanent editor are as follows:
+
+- Modifying file contents being previewed
+- Double clicking the preview tab
+- Performing a drag/drop operation of the editor preview tab resulting in the tab being moved.
+- Issuing a request to open the file being previewed (e.g. double clicking the file in the
+navigator)
+
+The preview editor is enabled by default when the extension is included in a Theia application, but
+may be disabled by modifying the preference:
+
+```json
+editor.enablePreview
+```
+
+In addition to this value, the preference:
+
+```json
+list.openMode
+```
+
+must be set to "singleClick" to enable opening files in preview mode.
