+HTTPS support
+-------------
+
+In order to support displaying maps over HTTPS, Overviewer loads the Google
+maps API and JQuery over HTTPS. This avoids security warnings for HTTPS
+sites, and is not expected to cause problems for users.
+
+If this change causes problems, take a look at the
+:ref:`custom web assets<customwebassets>` option. This allows you to
+provide a custom index.html which loads the required Javascript libraries
+over HTTP.
