     <strong>Structure Chooser</strong>
   </p>
 
-  The Structure Chooser interface provides a smart technique for
-  selecting PDB structures to view in Jalview by querying readily
-  available meta-data of structures. The Interface can be invoked by
-  selecting the
-  <strong>"3D Structure Data.."</strong> option from a sequence's
-  <a href="../menus/popupMenu.html">pop-up menu</a>. Some of the main
-  features it provides are listed below:
+  <p>
+    The Structure Chooser interface allows you to interactively select
+    which PDB structures to view for the currently selected set of
+    sequences. It's opened by selecting the <strong>"3D
+      Structure Data.."</strong> option from the Sequence ID panel's <a
+      href="../menus/popupMenu.html">pop-up menu</a>. The dialog
+    provides:
+  </p>
   <ul>
     <li>Automatic discovery, retrieval and association of PDB
-      entries for an alignment's sequences</li>
-    <li>Visualisation of discovered structures' meta-data</li>
-    <li>Ability to configure the meta-data entries to visualise</li>
-    <li>Auto-selection of the best structure via filtering by the
-      available metric parameters in the meta-data (i.e. resolution,
-      quality etc).</li>
-    <li>Selection of multiple structures in a single operation</li>
+      entries for sequences</li>
+    <li>Exploration of meta-data for available 3D structures</li>
+    <li>Automatic selection of the 'best structure' to display for
+      each sequence</li>
+    <li>Manual association of PDB entries by entering a PDB Id</li>
+    <li>Association of structure data from a local file (in mmCIF
+      or PDB format)</li>
   </ul>
-  Additionally, the Structure Chooser retains the following contemporary
-  features of Jalview:
-  <ul>
-    <li>Manual association of PDB entries via entering the PDB Id
-      or From File</li>
-    <li>Ability to view cached PDB entries</li>
-  </ul>
-
 
-  <strong>Associating PDB files with Sequences</strong>
-  <br> Discovery/Association of PDB entries to a sequence now
-  happens automatically during the initialisation of the Structure
-  Chooser Interface. Jalview uses the sequence's ID to query the PDB
-  Rest API provided by the EBI to discover PDB Ids associated with the
-  sequence.
-
-  <br>
-  <br>
-  <strong>Configuring displayed meta-data for Structures</strong>
-  <br> To configure the visible meta-data displayed for the
-  discovered structures, click the 'Configure Displayed Columns' tab,
-  then tick the options which you intend to make visible.
-
-  <br>
-  <br>
-  <strong>Auto-selection of best Structures</strong>
-  <br> Jalview can automatically filter and select the best
-  structures using various metric categories avaialble from the
-  meta-data of the structures. To perform this simply select any of the
-  following options from the drop-down menu in the Structure Chooser
-  interface: Best Uniprot coverage, Higest Resolution, Best Quality,
-  Highest Protein Chain etc. When the 'Invert' option is selected,
-  Jalview returns an inverse result for the current selected option in
-  the drop-down menu.
+  <p>
+    <strong>Automated discovery of structure data</strong>
+  </p>
+  <p>After selecting "3D Structure Data ..", Jalview queries the PDB
+    via the PDBe SOLR Rest API provided by EMBL-EBI to discover PDB ids
+    associated with the sequence. It does this based on the sequence's
+    ID string, and any other associated database IDs.</p>
+  <p>
+    <strong>Exploration of meta-data for available structures</strong>
+  </p>
+  <p>Information on each structure available is displayed in columns
+    in the dialog box. By default, only the title, resolution and PDB
+    identifier are shown, but many more are provided by the PDBe. To
+    configure which ones are displayed, select the 'Configure Displayed
+    Columns' tab and tick the columns which you want to see.</p>
+  <p>
+    <strong>Selection of the best structure for each sequence</strong>
+  </p>
+  <p>Jalview can automatically select the best structures according
+    to meta-data provided by the PDB. By default, the 'Best Quality'
+    structure for each sequence will be selected, but clicking on the
+    drop down menu allows other criteria to be chosen, including
+    Resolution (only defined for X-Ray structures), Highest Protein
+    Chain etc. When 'Invert' is selected, structures are selected in
+    reverse order for the current criteria (e.g. worst quality rather
+    than best).</p>

-      structures which have previously been downloaded/viewed using this
