+## Contributing changes
+
+After contributing your changes, please make sure to add a [changeset](https://github.com/changesets/changesets) describing your changes. This will help us in publishing new versions.
+
+## Publishing to npm
+
+We use [changesets](https://github.com/changesets/changesets) to make it easier to publish new versions. It handles common tasks like bumping version based on semver, creating tags and releases etc.

 ## Scripts
 
 - `lint` - runs linting on all JS/TS source files in the monorepo *[Turbo]* 
 - `gradle-plugin:lint` - runs linting on the Brownfield Gradle plugin source code
 - `typecheck` - runs TypeScript type checking on all TS source files in the monorepo *[Turbo]* 
 - `build` - runs all `build*` tasks in the Turbo repo - see below for more details *[Turbo]* 
+- `build:watch` - runs all `build:watch` tasks in all workspaces
 - `release` - releases a new version of React Native Brownfield package using `release-it`
 - `brownfield:plugin:publish:local` - publishes the Brownfield Gradle plugin to your local Maven repository for testing purposes
 - `build:brownfield` - builds the React Native Brownfield package (`packages/react-native-brownfield`) *[Turbo]*

+# Usage with Brownfield package
+
+The `brownie` CLI provides utilities for building & packaging artifacts for brownfield projects that use the `@callstack/react-native-brownfield` library.
+
+## Usage
+
+```bash
+brownie package:android --module-name :BrownfieldLib --variant release  # Package AAR with BrownfieldLib module in release variant
+brownie publish:android --module-name :BrownfieldLib                    # Publish all build variants of BrownfieldLib module to Maven local
+brownie package:ios --scheme BrownfieldLib --configuration Release      # Package XCFramework for BrownfieldLib scheme in Release configuration
+brownie codegen --help                                                  # Show help
+brownie --version                                                       # Show version
+```
+
+## iOS
+
+### Build for iOS
+
+Simply run `npx brownie package:ios` to create an XCFramework that you can later integrate into your native iOS app according to other instruction sections below.

+
+## Android
+
+For Android, building happens in two steps: first, you build (`brownie package:android`) the AAR artifact(s) with your module, in the appropriate build variant(s), and then you `brownie publish:android` them to Maven local.
+From there, native applications can consume your library from the local Maven repository.
+
+### Build for Android
+
+To build the artifact for Android without publishing, run `npx brownie package:android --module-name app`.
+
+Available arguments:
+
+| Argument      | Description                                                                                                                                  |
+| ------------- | -------------------------------------------------------------------------------------------------------------------------------------------- |
+| --variant     | Specify your app's build variant, which is constructed from build type and product flavor, e.g. 'debug' or 'freeRelease'. (default: "debug") |
+| --module-name | AAR module name                                                                                                                              |
+| --verbose     | Enable verbose logging                                                                                                                       |
+
+### Publish locally for Android
+
+To publish the `.aar`(s) built beforehand with `npx brownie publish:android` to Maven local, which will allow Gradle to be able to load it from Maven local repository, run:
+
+`npx brownie publish:android --module-name app`
+
+| Argument      | Description            |
+| ------------- | ---------------------- |
+| --module-name | AAR module name        |
+| --verbose     | Enable verbose logging |
