 CREATING / UPLOADING A CL
 -------------------------
 NOTE: The remainder of the tutorial assumes that your current working directory
 is the `src/` folder mentioned in <<_getting_the_code,Getting the code>>.
 
 Each CL corresponds exactly with a single branch in git. Any time you want to

 UPDATING THE CODE
 -----------------
 Inevitably, you'll want to pull in changes from the main Chromium repo. This is
 pretty easy with 'depot_tools':

 [NOTE]
 Running `git rebase-update` will update all your branches, but it will not
 automatically run `gclient sync` to update your dependencies.
 
 
 MANAGING MULTIPLE CLS
 ---------------------
 Sometimes you want to work on more than one CL at once (say, you have a CL
 posted for review and want to work on something else). For each CL that you
-want to work on, just use `git new-branch <branchname>`.

 Once you start to have more than one CL at a time, it can be easy to lose your
 bearings. Fortunately, 'depot_tools' has two tools to help you out:

 Additionally, sometimes you need to switch between branches, but you've got work
 in progress. You could use linkgit:git-stash[1], but that can be tricky to
 manage because you need to remember which branches you stashed what changes on.
