A Symphony extension enabling addition of documentation to any page in the backend, including user-defined section indexes and entry editors.

Documentation can be managed at System > Documentation. For each documentation item, specify:

1. The item's Title, used as the heading for the documentation drawer.
2. The item's Content.
3. The back-end Pages on which you'd like this item to appear.

1. Collapsible blocks: Documenter will automatically wrap the content between two h3 headlines into a collapsible block. The headline is used to toggle the state of the following block. All blocks are closed by default but Documenter stores the current opening state of all content blocks in the browser's localStorage and restores it on page refresh.

2. Notes: You can add notes that are highlighted and never collapsed by wrapping it in a div.note, e. g.:

    <div class="note"><strong>Note:</strong> I'm just here to look important.</div>
   

This extension is not a work of a single person, a lot of people tested it and contributed to it.
