Also familiarize yourself with the variables in the defaults/main.yml file or the Main Variables Wiki Page.

Technical Dependencies:

• Running Ansible/Tower setup (this role is tested against Ansible version 2.9.1 and newer)

• passlib (or python2-passlib, if using python2)
• python-lxml

All customizing should be done via the defaults/main.yml file or with extra vars within the project, job, workflow, etc. These variables can be found here in the Main Variables Wiki page.
