+Authorization Profiles
+======================
+
+Starting from CKAN 1.6.1, the harvester extension offers the hability to use
+different authorization profiles. These can be defined in your ini file as::
+
+    ckan.harvest.auth.profile = <profile_name>
+
+The two available profiles right now are:
+
+* `default`: This is the default profile, the same one that this extension has
+   used historically. Basically, only sysadmins can manage anything related to
+   harvesting, including creating and editing harvest sources or running harvest
+   jobs.
+
+* `publisher`: When using this profile, sysadmins can still perform any
+  harvesting related action, but in addition, users belonging to a publisher
+  (with role `admin`) can manage and run their own harvest sources and jobs.
+  Note that this requires CKAN core to also use the `publisher` authorization
+  profile, i.e you will also need to add::
+
+    ckan.auth.profile = publisher
+
+ To know more about the CKAN publisher auth profile, visit
+
+ http://wiki.ckan.org/Working_with_the_publisher_auth_profile
