Please see [this web page](http://docs.ansible.com/community.html) for community information, which includes pointers on how to ask questions on the mailing list and IRC.
The github issue tracker is not the best place for questions for various reasons, but both IRC and the mailing list are very helpful places for those things, and that page has the pointers to those.
Please see [this web page](http://docs.ansible.com/community.html) for information about the contribution process. Important license agreement information is also included on that page.
I'd also read the community page above, but in particular, make sure you copy [this issue template](https://github.com/ansible/ansible/blob/devel/ISSUE_TEMPLATE.md) into your ticket description. We have a friendly neighborhood bot that will remind you if you forget :) This template helps us organize tickets faster and prevents asking some repeated questions, so it's very helpful to us and we appreciate your help with it.
