 ## Methods
+
+### #accessible_for
+You can check if user has an access to the hierarchy by calling `accessible_for(user, options = {})` on hierarchy instance, eg:
+```ruby
+resource_hierarchy.accessible_for(user) # returns TRUE or FALSE
+```
+
+Optionally, you can pass an `options` argument to specify custom strategy.
+
