+<p><strong>DAS Settings</strong></p>
+<p>Jalview can retrieve and visualize features from many <a href="http://biodas.org/">DAS</a>
+ sources at once. The DAS sources are discovered and selected <em>via</em> the DAS settings panel.</p>
+<p><img src="das.gif">
+<p>The available sources are listed in the table using each source's
+Nickname as its identifier. Clicking on a source's entry in the table
+reveals more information about that service in the panel to the
+right. Select the tickbox in the "Use Source" column for a
+source to add it to the set Jalview queries for alignment and sequence
+features.
+</p>
+<p>You can filter the visible DAS sources by authority, type and "label".
+ You should read the DAS documentation to understand more about these values.
+<p><strong>Updating the list of sources</strong></p>
+<p>When the DAS Settings panel is first opened, and when the <strong>'Refresh
+ source'</strong> buton is pressed, a list of DAS sources
+ is retrieved from the DAS registry URL (set by default to the DAS
+ registration server at
+ http://das.sanger.ac.uk/registry/das1/sources/).</p>
+<p><strong>Adding your own DAS Sources</strong></p>
+<p>You can add your own DAS source to the list by clicking the "Add Local
+ Source" button. Enter the URL and nickname of your additional service.
+ It should be noted that Jalview 2.1 will not query additional sources for more
+ information, but this will be implemented in future editions.
