+** Running a local instance of mumi
+
+First copy some test mail data to be indexed:
+
+#+begin_src shell
+ $ cp -a tests/data data
+#+end_src
+
+Then, to have these emails indexed, run:
+
+#+begin_src shell
+ $ ./pre-inst-env mumi fetch
+#+end_src

+You should now be able to visit http://0.0.0.0:1234 in your browser
+and see your local mumi instance running.

+** Disabling browser caching
+
+If you modify the CSS or JavaScript source files, you'll want to make
+sure your browser doesn't keep cached copies. This can be done by
+changing a preference in the development tools menus, which is called
+something like "Disable cache (while DevTools is active)".
