Github workflow
===============

Fork a repo using github GUI, now there are 2 repos you are going to deal with, 1 the repo under your user bcoca/ansible and the main project ansible/ansible

* Clone the ansible repo (this is now 'origin'), the following assumes youre ssh keys are setup.
  There are several ways of doing this and organizing your workflow, this is just 'my way' and it can be used with several variations.
  Those with direct commit access might want to reverse this, you cannot count on direct pushes being rejected.

    #>git clone git@github.com:ansible/ansible
