 ## Warning
 
-Due to limitations of galaxy.ansible.com we had to move role to https://galaxy.ansible.com/cloudalchemy/node_exporter and use `_` instead of `-` in role name. This is a breaking change and unfortunatelly it affects all versions of node_exporter role as ansible galaxy doesn't offer any form of redirection. We are sorry for the inconvenience.

 ## Travis CI
 
-Combining molecule and travis CI allows us to test how new PRs will behave when used with multiple ansible versions and multiple operating systems. This also allows use to create test scenarios for different role configurations. As a result we have a quite large test matrix which will take more time than local testing, so please be patient.
