## Git tags

Don't forget to tag your work! After a merge request being accepted, run:

1 - (git tag -a "x.x.x" -m "") to create the new tag.
2 - (git push origin "x.x.x") to push the new tag to remote.

Follow the RubyGems conventions at http://docs.rubygems.org/read/chapter/7 to know how to increment the version number. Covered in more detail in http://semver.org/

## Merge requests acceptance

Don't forget to write tests to all your code. It's very important to maintain the codebase's sanity. Any merge request that doesn't have enough test coverage will be asked a revision
