If you are running a Confluence version prior to the 5.6.x ones, you can give a try to see how the add-on works. In the artemis documentation, you can find some pretty good details about the add-on: https://artemis.atlassian.net/wiki/display/RRFC/Road+Runner+for+Confluence+Home
However, if you are running a Confluence Cloud instance, I'm afraid that we could not use the add-on, if that's the one you mentioned, because in the Marketplace page for this add-on, it is only compatible until Confluence 5.6.x and the Cloud versions are in the latest versions of Confluence.
