+Decide on a non-privileged user
+===============================
+
+As MediaGoblin does not require any special permissions, you
+should either decide on a user to run it as, or even better create a
+dedicated user for it. Consult your distribution's documentation on
+how to create dedicated service user. Make sure it does have a locked
+password, so nobody can login using this user.
+
+You should create a working dir for MediaGoblin. We assume you will
+check things out into /srv/mediagoblin.example.org/mediagoblin/ for
+this documentation, but you can choose whatever fits your local needs.
+
+Most of the remaining documentation assumes you're working as that
+user. As root, you might want to do "su - mediagoblinuser".

 Install MediaGoblin and Virtualenv
