 # Folder Structure
-* `lib`: The project itself composed of:</br>
-`lib/android`: android sources and unit tests</br>
-`lib/ios`: iOS sources and unit tests</br>
-`lib/src`: javascript sources and unit tests</br>
-`lib/src/index.js`: the entry point for `import Navigation from 'react-native-navigation'`
-
-* `e2e`: [detox](https://github.com/wix/detox) iOS e2e tests (in the future, once detox supports it, we will have android e2e here as well)
-
-* `AndroidE2E`: Android e2e tests using native uiautomator
-
-* `playground`: The end-user project all e2e tests run against. Contains its own `src`, `android` and `ios`. Does not have its own package.json, depends on the local `<root>/lib` in order not to go through npm.
-
-* `integration`: misc javascript integration tests
-* `scripts`: all scripts

-
-`yarn run uninstall-android`: uninstalls playground from running android devices/simulators
-
-`yarn run test-js`: runs javascript tests and coverage report
-
-`yarn run test-watch`: runs javascript tests in watch mode (can also use the provided wallaby config)
