For choosing a good commit message, you try to answer the following w questions:
- what: fix, feature, delete, add
- where: the file or element you changed (e.g. Button)
- who: included already (git author)
- how: what exactly did you change?
- when: included already (commit timestamp)
- why: "in order to"
- (optional): reference to GitHub issue
Example:
fix(Button): change spacing in order to improve usability #25
You usually use present tense in commit messages.

If you use fix or closes in your commit message and reference a GitHub issue, it automatically creates a reference and closes the issue.
