How to contribute

Bug reports or feature requests

Open an issue with your bug report or feature request.

Create a fork
Push a commit with a meaningful message to your own fork.
If you have multiple commits related to the same feature, please consider squashing your commits into a single commit (e.g., git rebase -i HEAD~10)
Submit a pull request
Your pull request will not be accepted unless the commit passes all of the tests on Travis. If you want to run the complete build and tests locally before submitting a pull request, use Docker:
```
 $ cd /path/to/scrimmage
 $ docker build -t local/scrimmage:test -f ./ci/dockerfiles/ubuntu-16.04 .
```
