1. Check if your code follows the [coding conventions](https://github.com/RIOT-OS/RIOT/wiki/Coding-conventions). If the code does not comply these style rules, your code will not be merged.
2. The master branch should always be in a working state. The RIOT maintainers will create release tags based on this branch, whenever a milestone is completed.
3. Comments on a pull request should be added to the request itself, and *not* to the commit.
4. Keep commits to the point, e.g., don't add whitespace/typo fixes to other code changes. If changes are layered, layer the patches.
5. Describe the technical detail of the change(s) as specific as possible.
