 supposed that you, the user, works with a local repository named
 ``python`` that has an upstream remote repo named ``origin``. Your
 local repo has two branches ``v1`` and ``v2``. Usually the currently
-checked out branch is ``v2``.
+checked out branch is ``v2``. That is, it's assumed you did something
+like::
+
+    $ git clone -b v1 http://git.python.org/python.git
+    $ cd python
+    $ git fetch origin v2:v2
+    $ git checkout -b v2

+Commit editing and caveats
+==========================
+
+A warning not to edit published (pushed) commits also appears in
+documentation but it's also repeated here as it's very important.
+
+It is possible to recover from forced push but it's PITA for the
+entire team. Please avoid it.
+
+To see what commits have not been published yet compare the head of the
+branch with its upstream remote branch::
+
+    $ git log origin/v2..
+
+For every branch that has an upstream remote branch git maintains an
+alias @{upstream} (short version @{u})::
+
+    $ git log @{u}..
+    $ git log v1@{u}..v1
+
+To see the status of all branches::
+
+    $ git branch -avv
+
+To compare the status of local branches with remote repo::
+
+    $ git remote show origin
+
+Read `how to recover from upstream rebase
+<https://git-scm.com/docs/git-rebase#_recovering_from_upstream_rebase>`_.
+It is in ``git help rebase``.
+
+On the other hand don't be too afraid about commit editing. You can
+safely edit, remove, reorder, combine and split commits that hasn't
+been pushed yet. You can even push commits to your own (backup) repo,
+edit them later and force-push edited commits to replace what has
+already been pushed. Not a problem until commits are in a public
+repository.
