+Initial configuration
+---------------------
+
+This simple code is often appears in documentation, but it is
+important so let repeat it here::
+
+ $ git config --global user.name "User Name"
+ $ git config --global user.email user.name@example.org
+
+
+Examples in this PEP
+====================
+
+Examples of git commands in this PEP use the following approach. It is
+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``.
