no issue
- this prevents the need for running `npm/yarn install` inside the `lib/gh-koenig` directory
- `ember-cli` may eventually be able to handle this with an `ember install` or similar command, there's [an in-repo-addon RFC](638cad2405/active/0000-better-in-repo-addons.md) suggesting this improvement but it hasn't got much traction yet - it may be necessary to wait until ember-cli has standardised on `yarn`
