+# Tainacan Users Permissions
+
+This page explains how permissions are handled in Tainacan. What are the users roles available and what each one of them can do.
+
+Tainacan handles user permissions in the very same way WordPress does, so if you are used to WordPress Roles and Permissions, you wont have any trouble.
+
+Default WordPress roles are assigned with new capabilities to work with Collections, Items and other Tainacan specific operations. Additionaly Tainacan creates new roles, relative to the core WordPress roles, that have the same Tainacan specific capabilities, but dont have acces to the rest of the administrative panel of WordPress. For example, WordPress Editor can manage everything inside Tainacan, and they can also create and publish pages, in the other hand, Tainacan Editors can't.
+
+If you want to change permissions for specific roles or users, or even create new roles, you can allways use one of the many WordPress plugins available for that.
+
+In short, these are the roles and their main characteristics. A detailed description can be found in the next session. 
+
+* Subscriber: Can't really do anything inside tainacan.
+* Colaborator / Tainacan Colaborator: Can create items, but not to publish them.
+* Author / Tainacan Author: Can create and publish items, but can not edit published items nor edit other user's items.
+* Editor / Tainacan Editor: Can create, publish and edit other users's items.
+* Administrator: Rules the world.
+
+## Roles and permissions
+
+Here you will find a detailed explanation of what each role can do with each part of Tainacan.
+
+### Collections
+
+These are the capabilities related to collection management.
+
+**Note about Collection moderators**: Collection moderators have the same capabilities an editor has, but only in relation to the collections he or she is moderating. Even if the user is a subscriber, he will act as if he/she was an editor for that specific collection.
