| Contribution Guidelines |
| ####################### |
| |
| As an open-source project, we welcome and encourage the community to submit |
| patches directly to the project. In our collaborative open source environment, |
| standards and methods for submitting changes help reduce the chaos that can result |
| from an active development community. |
| |
| This document briefly summarizes the full `Contribution |
| Guidelines <http://docs.zephyrproject.org/contribute/contribute.html>`_ |
| documentation. |
| |
| * Zephyr uses the permissive open source `Apache 2.0 license`_ |
| that allows you to freely use, modify, distribute and sell your own products |
| that include Apache 2.0 licensed software. |
| |
| * There are some imported or reused components of the Zephyr project that |
| use other licensing and are clearly identified. |
| |
| * The Developer Certificate of Origin (DCO) process is followed to |
| ensure developers are following licensing criteria for their |
| contributions, and documented with a ``Signed-of-by`` line in commits. |
| |
| * Zephyr development workflow is supported on Linux, macOS, and Windows, |
| (with a few exceptions). |
| |
| * Source code for the project is maintained in the GitHub repo: |
| https://github.com/zephyrproject-rtos/zephyr |
| |
| * Issue and feature tracking is done using GitHub issues in this repo. |
| |
| * A Continuous Integration (CI) system runs on every Pull Request (PR) |
| to verify several aspects of the PR including Git commit formatting, |
| Coding Style, sanity checks builds, and documentation builds. |
| |
| * The `Zephyr devel mailing list`_ is a great place to engage with the |
| community, ask questions, discuss issues, and help each other. |
