 ### Guideline for Code Contributions
 
 * Use the [OneFlow](https://www.endoflineblog.com/oneflow-a-git-branching-model-and-workflow) model of development:
-  - Both new features and bug fixes should be developed in branches based on `master`.
+  - Both new features and bug fixes should be developed in branches based on `main`.
   - Hotfixes (critical bugs that need to be released *fast*) should be developed in a branch based on the latest tagged release.

+* Write code that is compatible with all supported versions of Python (listed in [pyproject.toml](https://github.com/glotzerlab/signac/blob/main/pyproject.toml)).
 * Avoid introducing dependencies -- especially those that might be harder to install in high-performance computing environments.
 * Create [unit tests](https://en.wikipedia.org/wiki/Unit_testing) and [integration tests](https://en.wikipedia.org/wiki/Integration_testing) that cover the common cases and the corner cases of the code.
 * Preserve backwards-compatibility whenever possible, and make clear if something must change.
