+= The refs/for namespace
+
+When pushing a new or updated commit to Gerrit, you push that commit using a
+link:https://www.kernel.org/pub/software/scm/git/docs/gitglossary.html#def_ref[reference],
+in the `refs/for` namespace. This reference must also define
+the target branch, such as `refs/for/[BRANCH_NAME]`.
+
+For example, to create a new change on the master branch, you would use the
+following command:
+
+....
+git push origin HEAD:refs/for/master
+....
+
+The `refs/for/[BRANCH_NAME]` syntax allows Gerrit to differentiate between
+commits that are pushed for review and commits that are pushed directly into
+the repository.
+
+Gerrit supports using either the full name or the short name for a branch. For
+instance, this command:
+
+....
+git commit
+git push origin HEAD:refs/for/master
+....
+
+is the same as:
+
+....
+git commit
+git push origin HEAD:refs/for/refs/heads/master
+....
+
+Gerrit uses the `refs/for/` prefix to map the concept of "Pushing for Review" to
+the git protocol. For the git client, it looks like every push goes to the same
+branch, such as `refs/for/master`.  In fact, for each commit pushed to this ref,
+Gerrit creates a new ref under a `refs/changes/` namespace, which Gerrit uses
+to track these commits. These references use the following format:
+
+....
+refs/changes/[CD]/[ABCD]/[EF]
+....
+
+Where:
+
+* [CD] is the last two digits of the change number
+* [ABCD] is the change number
+* [EF] is the patch set number
+
+For example:
+
+....
+refs/changes/20/884120/1
+....
+
+You can use the change reference to fetch its corresponding commit:
+
+....
+git fetch https://[GERRIT_SERVER_URL]/[PROJECT] refs/changes/[XX]/[YYYY]/[ZZ] \
+&& git checkout FETCH_HEAD
+....
+
+NOTE: The fetch command can be copied from the
+link:user-review-ui.html#download[download command] in the Change screen.
