 Sets the current head to the specified commit and optionally resets the
 index and working tree to match.
 
+This command is useful if you notice some small error in a recent
+commit (or set of commits) and want to redo that part without showing
+the undo in the history.
+
+If you want to undo a commit other than the latest on a branch,
+gitlink:git-revert[1] is your friend.

 OPTIONS
 -------
 --mixed::
-       Like --soft but reports what has not been updated. This is the
-       default action.
+       Resets the index but not the working tree (ie, the changed files
+       are preserved but not marked for commit) and reports what has not
+       been updated. This is the default action.
 
 --soft::
        Does not touch the index file nor the working tree at all, but
-       requires them in a good order.
+       requires them to be in a good order. This leaves all your changed
+       files "Updated but not checked in", as gitlink:git-status[1] would
+       put it.
 
 --hard::
        Matches the working tree and index to that of the tree being
-       switched to.
+       switched to. Any changes to tracked files in the working tree
+       since <commit-ish> are lost.
 
 <commit-ish>::
        Commit to make the current HEAD.
