### Commit Message Format
A commit message consists of a **header**, **body** and **footer**. The header has a **type**, **scope** and **subject**:
```
<type>(<scope>): <subject>
<BLANKLINE>
<body>
<BLANKLINE>
<footer>
```
The **header** is mandatory and the **scope** of the header is optional.
### Revert
If the commit reverts a previous commit, it should begin with `revert: `, followed by the header of the reverted commit. In the body it should say: `This reverts commit <hash>.`, where the hash is the SHA of the commit being reverted.
### Type
If the prefix is `feat`, `fix` or `perf`, it will appear in the changelog. However if there is any [BREAKING CHANGE](#footer), the commit will always appear in the changelog.
Other prefixes are up to your discretion. Suggested prefixes are `build`, `ci`, `docs` ,`style`, `refactor`, and `test` for non-changelog related tasks.
