-This tutorial demonstrates how to create a new Arvados pipeline using the Arvados Python SDK. The Arvados SDK supports access to advanced features not available using the @run-command@ wrapper, such as scheduling parallel tasks across nodes.

-h2. Setting up Git

-All Crunch scripts are managed through the Git revision control system. Before you start using Git, you should do some basic configuration (you only need to do this the first time):
+Start by creating a directory called @$USER@ . Next, create a subdirectory called @crunch_scripts@ and change to that directory:
-~$ git config --global user.name "Your Name"
-~$ git config --global user.email $USER@example.com
git@git.{{ site.arvados_api_host }}:$USER.git
-~$ cd $HOME # (or wherever you want to install)
-~$ git clone git@git.{{ site.arvados_api_host }}:$USER.git
-Cloning into '$USER'...

-h2. Creating a Crunch script
