+Enabling a theme
+~~~~~~~~~~~~~~~~
+
+To enable a theme, go to the Django theme admin page and select "Add site theme". You'll need to create a Site with the "domain" including the port. For the theme, specify the name of a subdirectory in one of the configured theme dirs. After this, the theme will immediately become available and enabled, and changes will show up live.
+
+For example, to enable the ``edx.org-next`` theme from the ``edx/edx-themes`` repo, you'd visit `<http://localhost:18000/admin/theming/sitetheme/>`_, use ``localhost:18000`` as the site domain, and specify ``edx.org-next`` as the theme directory.
