+<p><strong>DAS Sequence Feature Retrieval</strong></p>
+<p>Jalview includes a client for retrieving sequences and their features via
+the <a href="http://www.biodas.org">Distributed Annotation System</a>.</p>
+<ol>
+ <li>Open the Feature Settings panel by selecting "View ->
+ Feature Settings..."</li>
+ <li>Click on the "<a href="dassettings.html">DAS Settings</a>"
+ tabbed pane.</li>
+ <li>Select the sources to use for DAS feature retrieval, then
+ click the "Fetch DAS Features" button.
+ <ul>
+ <li>Cancelling Feature Retrieval<br>
+ Press the <strong>Cancel Fetch</strong> button to immediately stop
+ feature retrieval. This will not remove any features already added to
+ the alignment, but will halt any outstanding DAS requests.<em>The
+ cancel fetch button is of particular use when one or more DAS
+ annotation servers are not responding!</em>
+ </ul>
+ </li>
+</ol>
+<p>If your DAS source selection contains sources which use Uniprot
+accession ids, you will be asked whether Jalview should find Uniprot
+Accession ids for the given sequence names. It is important to realise
+that many DAS sources only use Uniprot accession ids, rather than
+Swissprot/Uniprot sequence names.<br>
+The <a href="../webservices/dbreffetcher.html">database reference
+fetcher</a> documentation describes how Jalview discovers what database
+references are appropriate for the sequences in the alignment.
+<ul>
+ <li><em>Note</em><br>
+ Please remember to save your alignment if either the start/end
+ numbering, or the sequence IDs were updated during the ID
+ retrieval process.</li>
+</ul>
+<p>
+<p><em>DAS support was introduced in Jalview Version 2.1.</em></p>
