 # ansible-logrotate-plusplus
 Ansible role which installs and configures logrotate
+It can test if paths exist before writing a logrotate config to the server.
+Load the roles default vars with custom paths and per path parameters, and run the playbook across a dynamic
+infrastructure and only write logerotate rules to the appropriate system with the correct paths present.
+
+This project was based of https://github.com/arillso/ansible.logrotate 1.5.2
+(https://github.com/arillso/ansible.logrotate/commit/038649f7933c21ba9f1f2c8363bfb4d49aaf46f2)
