:# Confirm and review the Ansible package installed on matrix.senecacollege.ca
== Part 4: Gather software and hardware information available on remote machine ==
: One of the main core ansible module is called "setup", it is automatically called by ansible playbook to gather useful "facts" about remote hosts that can be used in ansible playbooks. It can also be executed directly by the ansible command (/usr/bin/ansible) to check out what "facts" are available to on a remote host.
