 ## Authorization vs Authentication
-Authentication is determining if a user is who they say they are. Authorization is determining whether or not said user is allowed to access / interact with the resource. This module assumes you've already handled authentication.

-The function is looking against the JSON for either a name match to the same or higher depth of the ACL string, a boolean true, or a "*" at the same or higher level. For example, with the above given permission JSON, the ACL string of "products:toys" blocking a route that should have "action_figures" in the ACL string will allow the user through.
+The function looks through the permission object for a boolean true, or a string match or "*" at the same or higher level of the ACL string.

+Be carefull with your permissions to ensure that you check them at the level you really want. For example, using the ACL string of "products:toys" with the above permissions object, attempting to protect a route that should require "action_figures" will pass, even though that isn't your intent. To get the granularity of check you want here, you need to use an ACL like "products:toys:action_figures".
 
 # The CanThey Function

 ## Parameters
 
-* requiredACL - Required. The access level required, in a string of similar format to above..
-* givenUserPermissions - Required. The JSON representation of the user's permissions OR an array of JSON permissions.
-	* if this is an array, an internal function called canTheyCombiner is used to create a singular permissions object from many permissions objects. A great example of this is if you used role based permisisons and a user had many roles.
+* requiredACL - Required. The access level required, as a string with or without splitBy characters.
+* givenUserPermissions - Required. A JSON permissions object or array of permissions objects.
+	* If array, canTheyCombiner merges objects into a single permissions object prior to ACL comparision. A use case for this is for role based permisisons where a user has many roles.
 * opts - Optional. Each attribute in opts is optional, with a default value.
