One of the most important things we do with Ansible is enable community contribution. However, too often contribution is weighed to be all about software code.
The previous “contributing” information on github didn’t give very good info about other kinds of non-code contributions, so we’ve set up a new document. This also includes information about the mailing lists, ways to report bugs (also a form of contribution) and so on.
I don’t think anything really has changed here, but it’s good to share this more explicitly – and I should say this document is a work in progress and also open source. If you have suggestions please let us know, and if you find a typo, it takes pull requests too
