  ## Local development with galoy-client
  The mobile app uses the [galoy-client](https://github.com/GaloyMoney/galoy-client) for communication with the galoy API and translations. If you want to make changes to the galoy-client locally to test changes in the app e.g. you want to add a key to the translations file this is the steps you should take. Since the metro bundler [does not support](https://github.com/facebook/metro/issues/68) `yarn link`, we have to use [yalc](https://www.npmjs.com/package/yalc).
