  3. Your ticket is a Help Wanted GitHub issue for the Mattermost project you’re contributing to.

    • If not, follow the process here.
  4. Your code is thoroughly tested, including appropriate unit, end-to-end, and integration tests for webapp.

  5. If applicable, user interface strings are included in localization files:

    5.1. In the webapp repository run make i18n-extract to generate the new/updated strings.

  6. The PR is submitted against the Mattermost master branch from your fork.

  7. The PR title begins with the Jira or GitHub ticket ID (e.g. [MM-394] or [GH-394]) and summary template is filled out.

  8. If your PR adds or changes a RESTful API endpoint, please update the API documentation.

  9. If your PR adds a new plugin API method or hook, please add an example to the Plugin Starter Template.

  10. If QA review is applicable, your PR includes test steps or expected results.

  11. If the PR adds a substantial feature, a feature flag is included. Please see criteria here.

  12. Your PR includes basic documentation about the change/addition you’re submitting. View our guidelines for more information about submitting documentation and the review process.

Once submitted, the automated build process must pass in order for the PR to be accepted. Any errors or failures need to be addressed in order for the PR to be accepted. Next, the PR goes through code review. To learn about the review process for each project, read the CONTRIBUTING.md file of that GitHub repository.

That’s all! If you have any feedback about this checklist, let us know in the Contributors channel.
