 # Diff
-
 The diff module is used to show differences between content revisions.
+It replaces the normal Revisions tab seen when administering nodes.
 
-This port to Backdrop requires more testing.
+Diff enhances the listing of revisions with an option to view the differences 
+between any two content revisions and revert back to older versions.
 
-This is a port from the Drupal module of the same name. 
+Access to this feature is controlled with the 'View revisions' permission. 
+The feature can be enabled/disabled with 'Compare revisions' settings available 
+on the configuration page for each content type. 
 
+It also provides a predefined block 'Inline differences' that can be added 
+to any layout by using Backdrop's layout administration.
+
+This is a port from the Drupal module of the same name, currently version 7.x-3.4.
