     <li><em><font size="3">Maximum memory limit</em><br/>
       Since 2.11.1.0, Jalview's configuration includes a 'maximum memory limit':
       <pre>jalview.jvmmemmax = 32G</pre>
-      Adjusting this default (via a JVL file, above) will allow larger amounts of memory to be allocated to Jalview in connjunction with the jalview.jvmmempc setting. 
+      Adjusting this default (via a JVL file, above) will allow larger amounts (or can limit the amount) of memory to be allocated to Jalview in conjunction with the jalview.jvmmempc setting.

+      If you are using the Jalview standalone executable jar, (usually named <em>jalview-all-....jar</em> with a Jalview and Java version designation),
+      then you can set the <em>jvmmempc</em> and <em>jvmmemmax</em> values using application command line arguments <em>-jvmmempc=N</em>
+      and <em>-jvmmemmax=M</em> respectively, e.g.
+      <pre>java -jar jalview-all-2.11.1.0-j1.8.jar -jvmmempc=50 -jvmmemmax=20g</pre>
+      (this example will launch Jalview with a maximum heap size of the smaller of 20GB or 50% of physical memory detected).
