feat: --packageManager=XYZ

 And `--comment=off` would turn off comments for maintainers who prefer minimal pull requests.
 
+To customize which package manager is reflected in the comments, use the `--packageManager=XYZ` flag. XYZ can be one of the following: npm (default), pnpm, yarn, or bun.
+
 For repositories with many packages, comments might get too long. In that case, you can use `--only-templates` to only show templates.
 
 pkg.pr.new uses `npm pack --json` under the hood, in case you face issues, you can also use the `--pnpm` flag so it starts using `pnpm pack`. This is not necessary in most cases.
