 DESCRIPTION
 -----------
 
 When <paths> are not given, this command switches branches by
-updating the index and working tree to reflect the specified
-branch, <branch>, and updating HEAD to be <branch> or, if
-specified, <new_branch>.  Using -b will cause <new_branch> to
-be created; in this case you can use the --track or --no-track

+branch.
 
-As a convenience, --track will default to create a branch whose
-name is constructed from the specified branch name by stripping
-the first namespace level.
+If `-b` is given, a new branch is created and checked out, as if
+linkgit:git-branch[1] were called; in this case you can
