 ## Usage
 
 ### Via Django admin
 
-1. Go to `/admin/clearcache/`, you should see a form with cache selector
+Clearcache can be used by any user with permission ```clearcache.use_clearcache```, 
+and obviously be any superuser (superusers have all permissions).
+
+1. Go to `/admin/clearcache/`. If you are authorized, you should see a form with cache selector.
 2. Pick a cache. Usually there's one default cache, but can be more.
 3. Click the button, you're done!
 
+Any user with access to the Admin interface (i.e. any user with `is_staff` privilege) 
+will see a Clearcache section on the Admin homepage, if he is authorized, and can 
+access Clearcache from there. 
+

 ### Via manage.py command
