There are two branches in this repository. I used long lived branches to segregate between different articles, and tags along each branch to make it possible to go to a certain milestone in the tutorial. (If you think this ended up being to complicated, then drop me a note/message so I can get feedback on your experience.)
The code in Master branch, goes with an article about getting started with Ansible on MacOS: https://confessionsofanagilecoach.blogspot.com/2019/05/enterprise-network-configuration-as.html
The code in playbook_tutorial branch goes with with article: https://confessionsofanagilecoach.blogspot.com/2019/06/ansible-playbooks-and-modules.html
