| # How to Contribute |
| |
| CoreOS projects are [Apache 2.0 licensed](LICENSE) and accept contributions via |
| GitHub pull requests. This document outlines some of the conventions on |
| development workflow, commit message formatting, contact points and other |
| resources to make it easier to get your contribution accepted. |
| |
| # Certificate of Origin |
| |
| By contributing to this project you agree to the Developer Certificate of |
| Origin (DCO). This document was created by the Linux Kernel community and is a |
| simple statement that you, as a contributor, have the legal right to make the |
| contribution. See the [DCO](DCO) file for details. |
| |
| # Email and Chat |
| |
| The project currently uses the general CoreOS email list and IRC channel: |
| - Email: [coreos-dev](https://groups.google.com/forum/#!forum/coreos-dev) |
| - IRC: #[coreos](irc://irc.freenode.org:6667/#coreos) IRC channel on freenode.org |
| |
| Please avoid emailing maintainers found in the MAINTAINERS file directly. They |
| are very busy and read the mailing lists. |
| |
| ## Getting Started |
| |
| - Fork the repository on GitHub |
| - Read the [README](README.md) for build and test instructions |
| - Play with the project, submit bugs, submit patches! |
| |
| ## Contribution Flow |
| |
| This is a rough outline of what a contributor's workflow looks like: |
| |
| - Create a topic branch from where you want to base your work (usually master). |
| - Make commits of logical units. |
| - Make sure your commit messages are in the proper format (see below). |
| - Push your changes to a topic branch in your fork of the repository. |
| - Make sure the tests pass, and add any new tests as appropriate. |
| - Submit a pull request to the original repository. |
| |
| Thanks for your contributions! |
| |
| ### Format of the Commit Message |
| |
| We follow a rough convention for commit messages that is designed to answer two |
| questions: what changed and why. The subject line should feature the what and |
| the body of the commit should describe the why. |
| |
| ``` |
| scripts: add the test-cluster command |
| |
| this uses tmux to setup a test cluster that you can easily kill and |
| start for debugging. |
| |
| Fixes #38 |
| ``` |
| |
| The format can be described more formally as follows: |
| |
| ``` |
| <subsystem>: <what changed> |
| <BLANK LINE> |
| <why this change was made> |
| <BLANK LINE> |
| <footer> |
| ``` |
| |
| The first line is the subject and should be no longer than 70 characters, the |
| second line is always blank, and other lines should be wrapped at 80 characters. |
| This allows the message to be easier to read on GitHub as well as in various |
| git tools. |
