And add MatrixOne repo as a remote repository with:

  1. git remote add upstream https://github.com/matrixorigin/matrixone.git

3. Create a new branch, the branch name is up to you.

  1. git checkout -b topic-branch

4. Commit changes to your own branch locally, add necessary unit tests.

5. Push to a new branch in your own fork.

  1. git push origin main:NEW_BRANCH

7. Once your PR get approved, it would be merged sooner. After merging, synchronize your local repository.

  1. git pull --force upstream main:main

8. Synchronized the main branch of your remote repository in Github.

  1. git push --force origin main:main

If you still have some trouble, please refer to GitHub Docs for help.

Code review

When you open a pull request, you can assign some reviewers, or just leave it blank. And you can add some related labels so that it would be easier to recognize the PR’s type/priority/etc. During reviewing, reviewers would comment on your code snippet, you could modify the code on your topic branch locally, commit the changes, and push to GitHub, the new commits would be attached to the PR automatically.
