## Committing
This project uses [semantic release](https://github.com/semantic-release/semantic-release) to ensure version bumps
follow semver so that projects depending on it don't break unexpectedly.
In order to automatically determine version updates, semantic release expects commit messages to follow the
[conventional-changelog](https://github.com/bcoe/conventional-changelog-standard/blob/master/convention.md)
specification.
You can use the [commitizen CLI](https://github.com/commitizen/cz-cli) to make commits formatted in this way:
```bash
npm install -g commitizen@latest cz-conventional-changelog@latest
```
Now you're ready to make commits using `git cz`.
