Code contributions

Your first issue

  1. Read the project’s README.md to learn how to setup the development environment.

  2. Find an issue to work on. The best way is to look for the good first issue or help wanted labels.

  3. Comment on the issue to say that you are going to work on it.

  4. Code! Make sure to update unit tests!

  5. When done, create your pull request.

  6. Verify that CI passes all status checks. Fix if needed.

  7. Wait for other developers to review your code and update code as needed.

  8. After your pull request is reviewed and approved, an NVIDIA-Merlin team member merges it.

Remember, if you are unsure about anything, don’t hesitate to comment on issues and ask for clarifications!

Seasoned developers

After you have your feet wet and are comfortable with the code, you can look at the prioritized issues of our next release in our project boards.

Pro Tip: Always look at the release board with the highest number for issues to work on. This is where the NVIDIA-Merlin developers also focus their efforts.

Look at the unassigned issues, and find an issue you are comfortable with contributing to. Start with Step 3 from above, commenting on the issue to let others know that you are working on it. If you have any questions related to the implementation of the issue, ask them in the issue instead of the PR.
