-### Playground app Folder Structure
+### Project Folder Structure
 
 | Folder | Description |
 | ------ | ----------- |
-| `lib` | The project itself composed of: |
-| `lib/android` | android sources and unit tests |
-| `lib/ios` | iOS sources and unit tests |
-| `lib/src` | TypeScript sources and unit tests |
-| `lib/dist` | compiled javascript sources and unit tests |
-| `lib/dist/index.js` | the entry point for `import Navigation from 'react-native-navigation'` |
-| `e2e` | [detox](https://github.com/wix/detox) e2e tests on both Android and iOS |
-| `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` for faster local development (no need to `npm install` locally). |
-| `integration` | misc javascript integration tests, proving integration with other libraries like redux |
-| `scripts` | all scripts |
+| `src` | TypeScript sources and unit tests |
+| `android` | Android sources and unit tests |
+| `ios` | iOS sources and unit tests |
+| `lib` | Compiled JavaScript and TypeScript definitions (generated by `react-native-builder-bob`) |
+| `lib/module/index.js` | The entry point for `import Navigation from 'react-native-navigation'` |
+| `playground` | The playground app workspace. Contains its own `src`, `android`, `ios`, and `package.json`. All e2e tests run against this app. |
+| `playground/e2e` | [detox](https://github.com/wix/detox) e2e tests on both Android and iOS |

 ### Scripts
 
+This project uses [Yarn workspaces](https://yarnpkg.com/features/workspaces). The root workspace contains the main library, and the `playground` workspace contains the playground app for testing.
