 - `message` - The commit message used for the version bump. Any `%s` in the string will be replaced with the new version. By default, npm uses `%s` and Yarn uses `v%s`.
+- `packageManager` - Set the package manager to be used. Defaults to the [packageManager field in package.json](https://nodejs.org/api/packages.html#packagemanager), so only use if you can't update package.json for some reason.

+### Package Managers
+
+If a package manager is not set in package.json, via configuration (`packageManager`), or via the CLI (`--package-manager`), `np` will attempt to infer the best package manager to user by looking for lockfiles. But it's recommended to set the [`packageManager` field](https://nodejs.org/api/packages.html#packagemanager) in your package.json to be consistent with other tools. See also [corepack docs](https://nodejs.org/api/corepack.html).

 ### Publish with a CI
 
 If you use a Continuous Integration server to publish your tagged commits, use the `--no-publish` flag to skip the publishing step of `np`.
