The whole purpose of an inventory source is to have systems to manipulate. The manipulation comes from playbooks (or, in the case of Ansible ad hoc execution, that is, simple single-task plays). You should already have a basic understanding of playbook construction, so we won't spend a lot of time covering that; however, we will delve into some specifics of how a playbook is parsed. Specifically, we will cover the following:

• Order of operations
• Relative path assumptions
• Play behavior keys
• Host selection for plays and tasks
• Play and task names
