# Contributing to mat2

The main repository for mat2 is on [0xacab]( https://0xacab.org/jvoisin/mat2 ),
but you can send patches to jvoisin by [email](https://dustri.org/) if you prefer.

Do feel free to pick up [an issue]( https://0xacab.org/jvoisin/mat2/issues )
and to send a pull-request. Please do check that everything is fine by running the
testsuite with `python3 -m unittest discover -v` before submitting one :)

If you're fixing a bug or adding a new feature, please add tests accordingly,
this will greatly improve the odds of your merge-request getting merged.

If you're adding a new fileformat, please add tests for:

1. Getting metadata
2. Cleaning metadata
3. Raising `ValueError` upon a corrupted file

Since mat2 is written in Python3, please conform as much as possible to the
[pep8]( https://pep8.org/ ) style; except where it makes no sense of course.
