 It is possible to use bookmark names in every revision lookup (e.g. hg
 merge, hg update).
+
+The bookmark extension offers the possiblity to have a more git-like experience
+by adding the following configuration option to your .hgrc:
+
+[bookmarks]
+track.current = True
+
+This will cause bookmarks to track the bookmark that you are currently on, and
+just updates it. This is similar to git's approach of branching.
