We follow a +simple 'inbound=outbound' model for contributions: the act of submitting an +'inbound' contribution means that the contributor agrees to license the code +under the same terms as the project's overall 'outbound' license - in our +case, this is almost always Apache Software License v2 (see LICENSE). + +How to contribute +~~~~~~~~~~~~~~~~~ + +The preferred and easiest way to contribute changes to Matrix is to fork the +relevant project on github, and then create a pull request to ask us to pull +your changes into our repo +(https://help.github.com/articles/using-pull-requests/) + +**The single biggest thing you need to know is: please base your changes on +the develop branch - /not/ master.** + +We use the master branch to track the most recent release, so that folks who +blindly clone the repo and automatically check out master get something that +works. Develop is the unstable branch where all the development actually +happens: the workflow is that contributors should fork the develop branch to +make a 'feature' branch for a particular contribution, and then make a pull +request to merge this back into the matrix.org 'official' develop branch. We +use github's pull request workflow to review the contribution, and either ask +you to make any refinements needed or merge it and make them ourselves. The +changes will then land on master when we next do a release. + +We use Jenkins for continuous integration (http://matrix.org/jenkins), and +typically all pull requests get automatically tested Jenkins: if your change breaks the build, Jenkins will yell about it in #matrix-dev:matrix.org so please lurk there and keep an eye open. + +Code style +~~~~~~~~~~ + +All Matrix projects have a well-defined code-style - and sometimes we've even +got as far as documenting it... For instance, synapse's code style doc lives +at https://github.com/matrix-org/synapse/tree/master/docs/code_style.rst. + +Please ensure your changes match the cosmetic style of the existing project, +and **never** mix cosmetic and functional changes in the same commit, as it +makes it horribly hard to review otherwise. + +Attribution +~~~~~~~~~~~ + +Everyone who contributes anything to Matrix is welcome to be listed in the +AUTHORS.rst file for the project in question. Please feel free to include a +change to AUTHORS.rst in your pull request to list yourself and a short +description of the area(s) you've worked on. Also, we sometimes have swag to +give away to contributors - if you feel that Matrix-branded apparel is missing +from your life, please mail us your shipping address to matrix at matrix.org and we'll try to fix it :) + +Sign off +~~~~~~~~ + +In order to have a concrete record that your contribution is intentional +and you agree to license it under the same terms as the project's license, we've adopted the +same lightweight approach that the Linux Kernel +(https://www.kernel.org/doc/Documentation/SubmittingPatches), Docker +(https://github.com/docker/docker/blob/master/CONTRIBUTING.md), and many other +projects use: the DCO (Developer Certificate of Origin: +http://developercertificate.org/).

Matrix is a very open and collaborative project as you might expect given our obsession with open communication. If we're going to successfully matrix together all the fragmented communication technologies out there we are reliant on contributions and collaboration from the community to do so.
