Contributing to Kakunin

This section will guide you through the contribution process.

Step 1: Fork

Fork the project on GitHub and clone your fork locally.

git clone
cd Kakunin
git remote add upstream

Which branch?

For developing new features and bug fixes, the master branch should be pulled and built upon.

Step 2: Branch

Create a branch and start hacking:

git checkout -b my-branch -t origin/master

Step 3: Commit

Make sure git knows your name and email address:

git config --global "Jan Kowalski"
git config --global ""

Add and commit:

$ git add my/changed/files
$ git commit

Commit message guidelines

The commit message should describe what changed and why. We don't put any constraints on message format although it should clearly describe the change.

  1. If your patch fixes an open issue, you can add a reference to it at the end of the log. Use the Fixes: prefix and the full issue URL. For other references use Refs:.


    • Fixes:
    • Refs:
    • Refs:

Step 4: Rebase

Use git rebase (not git merge) to synchronize your work with the main repository.

$ git fetch upstream
$ git rebase upstream/master

Step 5: Test

Bug fixes and features should come with tests. Looking at other tests to see how they should be structured can help.

To run the tests just run the default command:

npm test

Make sure the linter does not report any issues and that all tests pass. Please do not submit patches that fail either check.

Step 6: Push

git push origin my-branch

Pull requests are usually reviewed within a few days.

Step 7: Discuss and update

You will probably get feedback or requests for changes to your Pull Request. This is a big part of the submission process so don't be discouraged!

To make changes to an existing Pull Request, make the changes to your branch. When you push that branch to your fork, GitHub will automatically update the Pull Request.

Feel free to post a comment in the Pull Request to ping reviewers if you are awaiting an answer on something.

Step 8: Landing

In order to land, a Pull Request needs to be reviewed and approved by at least one Kakunin Collaborator and pass all test. After that, as long as there are no objections from a Collaborator, the Pull Request can be merged.

After you push new changes to your branch, you need to get approval for these new changes again, even if GitHub shows "Approved" because the reviewers have hit the buttons before.
