+<body>
+<p><strong>DAS Settings</strong></p>
+<p>Jalview can retrieve sequences and features from many <a
+ href="http://biodas.org/">DAS</a> sources. The DAS sources that
+it uses are discovered and selected <em>via</em> the DAS settings panel,
+opened either from the <a href="featuresettings.html">View→Feature
+Settings</a> dialog box from the alignment window's menu bar, or the <a
+ href="featuresettings.html">Tools→Preferences</a> dialog box
+opened from the Desktop menu bar.</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://www.dasregistry.org/das/).</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.
