5 # It should live in /etc/ansible/hosts
6 #
7 # - Comments begin with the '#' character
8 # - Blank lines are ignored
9 # - Groups of hosts are delimited by [header] elements
10 # - You can enter hostnames or ip addresses
11 # - A hostname/ip can be a member of multiple groups
12 #
13 # Ex 1: Ungrouped hosts, specify before any group headers.
