| We require pull request titles to follow the [Conventional Commits specification](https://www.conventionalcommits.org/en/v1.0.0/) | |
| and it looks like your proposed title needs to be adjusted. | |
| Your title should look like this. The scope field is optional. | |
| ``` | |
| <type>(<scope>): <description> | |
| ``` | |
| If the PR includes a breaking change, mark it with an exclamation mark: | |
| ``` | |
| <type>!: <description> | |
| ``` | |
| and include a "BREAKING CHANGE:" footer in the body of the pull request. | |
| Details: | |
