+What are facts? 
+- Facts are information discovered by Ansible about a target system
+- There are two ways facts are collected:
+  - Using the setup module with an ad-hoc command: `ansible all -m setup`
+  - Facts are gathered by default when a playbook is executed 
+- Fact gathering in playbooks may be disabled using the **gather_facts** attribute
