I don't want to add a dependency between the file and the plugin version - that's what we have `git` for: if you browse files on Github you will always see a README that is in sync with whatever version the plugin is at (which can be checked by looking at the gradle build file).

That would be ok.  I knew there was at least a version 1.10 out there somewhere, but this only said 0.3, so figured this was an abandoned repo.
