+=== Our stance on multiple roles per user
+
+We believe that you should only distinguish roles that have different ways of resolving their permissions. A typical set of roles would be
+
+* anonymous guest (has access to nothing with some exceptions)
+* signed up user (has access to some things depending on its attributes and associations)
+* administrator (has access to everything)
+
+We don't do multiple, parametrized roles like &quot;leader for project #2&quot; and &quot;author of post #7&quot;. 
+That would be reinventing associations. Just use a single :user role and let your permission block
+query regular associations and attributes.
