+## 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.
