 ### Auto-releasing and commit conventions
 
 A new version of this package will be automatically published whenever there is a merge to the `main` branch. Specifically, new GitHub releases and tags will be created, and a new NPM package version will be published. The release version increment type is derived from the format of the commit messages that were bundled in the merge to `main`, using [semantic-release commit message conventions](https://github.com/semantic-release/semantic-release#commit-message-format).
