-  <p>From version 2.11.2, Jalview includes a <strong>launching shell script</strong> which is the recommended way to
-  launch an installed Jalview application from the command line.  It supports all the <a href="clarguments.html">command line arguments</a>

+  <p>There are a few different ways to do this:</p>

+    <li>Use the <strong>jalview</strong> command that links to a <strong>launch
+        script</strong>. Launch scripts are available if you are running an up to
+      date version of Jalview (at least 2.11.2.0), or have installed
+      Jalview via a package manager (e.g. conda, homebrew, apt).
+    </li>
+    <li>Embed arguments in a <strong>.JVL</strong> file. These
+      files will be opened automatically by the Jalview application when
+      double-clicked in a file browser on Windows and OSX.

+    <li>Execute the Jalview standalone Jar file with an existing
+      Java installation</li>
