 When <paths> are given, this command does *not* switch
 branches.  It updates the named paths in the working tree from
-the index file (i.e. it runs `git checkout-index -f -u`), or
-from a named commit.  In
-this case, the `-f` and `-b` options are meaningless and giving
+the index file, or from a named commit.  In
+this case, the `-b` options is meaningless and giving
 either of them results in an error.  <tree-ish> argument can be
 used to specify a specific tree-ish (i.e. commit, tag or tree)
 to update the index for the given paths before updating the
 working tree.
 
+The index may contain unmerged entries after a failed merge.  By
+default, if you try to check out such an entry from the index, the
+checkout operation will fail and nothing will be checked out.
+Using -f will ignore these unmerged entries.  The contents from a
+specific side of the merge can be checked out of the index by
+using --ours or --theirs.  With -m, changes made to the working tree
+file can be discarded to recreate the original conflicted merge result.
