Use a consistent style
The Code style section of the documentation sets the style guidelines for HOOMD-blue code.
Document code with comments
Use doxygen header comments for classes, functions, etc. Also comment complex sections of code so that other developers can understand them.
Compile without warnings
Your changes should compile without warnings.
Write unit tests
Add unit tests for all new functionality.
The developer should run research-scale simulations using the new functionality and ensure that it behaves as intended.
Write user documentation
Document public-facing API with Python docstrings in Google style.
Document version status
Add versionadded, versionchanged, and deprecated Sphinx directives to each user-facing Python class, method, etc., so that users will be aware of how functionality changes from version to version. Remove this when breaking APIs in major releases.
Add developer to the credits
Update the credits documentation to list the name and affiliation of each individual that has contributed to the code.
