+# Setting up a development environment
+
+The Liquid Swap SDK React Native plugin consumes the underlying Liquid Swap SDK from the following sources:
+
+-   For iOS: The Liquid Swap SDK Swift bindings are integrated via CocoaPods.
+-   For Android: The Liquid Swap SDK Android bindings are integrated via Jitpack.
+
+When developing, it can be useful to work with a locally built version of the Liquid Swap SDK instead of relying on what is published already on CocoaPods / Jitpack.
+To do this, you first need to build the Liquid Swap SDK bindings locally and then point the plugin to make use of the locally built Liquid Swap SDK bindings.
+
+All the following commands can be run in the `lib/ls-sdk-react-native` directory.
+
+## Prerequisites
+
+Set the ANDROID_NDK_HOME env variable to your SDK home directory:
+```
+export ANDROID_NDK_HOME=<your android ndk directory>
+```
+
+To lint the result of the code generation ktlint, swiftformat and tslint need to be installed:
+```bash
+brew install kotlin ktlint swiftformat
+yarn global add tslint typescript
+```
+
+On first usage you will need to run:
+```bash
+make init
+```
+
+## Building the bindings
+
+Then to build and copy the Kotlin, Swift and React Native bindings into the React Native package run:
+```bash
+make all
+```
+
+This will generate the following artifacts:
+
+- iOS
+	- `ios/LiquidSwapSDKMapper.swift`
+	- `ios/LiquidSwapSDK.m`
+	- `ios/LiquidSwapSDK.swift`
+	- `ios/bindings-swift/ls_sdkFFI.xcframework`
+	- `ios/bindings-swift/Sources/LiquidSwapSDK/LiquidSwapSDK.swift`
+- Android
+	- `android/src/main/java/com/lssdk/ls_sdk.kt`
+	- `android/src/main/java/com/lssdk/LiquidSwapSDKMapper.kt`
+	- `android/src/main/java/com/lssdk/LiquidSwapSDKModule.kt`
+	- `android/src/main/jniLibs/arm64-v8a/libls_sdk_bindings.so`
+	- `android/src/main/jniLibs/armeabi-v7a/libls_sdk_bindings.so`
+	- `android/src/main/jniLibs/x86/libls_sdk_bindings.so`
+	- `android/src/main/jniLibs/x86_64/libls_sdk_bindings.so`
+- Typescript
+	- `src/index.ts`
+
+### Building for one platform only
+
+You can also build for Android or iOS only, in that case run:
+```bash
+make android react-native
+```
+or
+```bash
+make ios react-native
+```
+
+## Using the locally built bindings
+
+To use the locally built bindings instead of integrating them remotely, make the following changes:
+
+- For iOS:
+	- Rename the podspec files in `lib/ls-sdk-react-native/`:
+		- Rename `ls_sdk.podspec` to `ls_sdk.podspec.prod`
+		- Rename `LiquidSwapSDK.podspec.dev` to `LiquidSwapSDK.podspec`
+- For Android:
+	- Comment out the following line from the dependencies section in `lib/ls-sdk-react-native/android/build.gradle`:
+		- `implementation("com.github.breez:breez-sdk-liquid:${getVersionFromNpmPackage()}") { exclude group:"net.java.dev.jna" }`
+
+Reinstall the dependencies in the example project and run it.
+It will now use the locally built bindings.
+
+## Testing with the example app
+
+To test locally built bindings in the example app, the npm dependencies need to be updated to use the local package.
+In `lib/ls-sdk-react-native/example/package.json` replace the current version with `file:../`:
+```json
+    "@breeztech/react-native-liquid-swap-sdk": "file:../",
+```
+
+Run the npm/yarn install to download dependences for both the react-native-liquid-swap-sdk package and the example app:
+```bash
+yarn bootstrap
+```
+
+Finally in the `lib/ls-sdk-react-native/example/` directory start either the iOS or Android app:
+```bash
+yarn android
+```
+or for iOS:
+```bash
+yarn ios
+```
+
+## Troubleshooting
+
+In case you get an error like: 
+> java.lang.RuntimeException: Unable to load script. Make sure you're either running Metro (run 'npx react-native start') or that your bundle 'index.android.bundle' is packaged correctly for release. 
+
+Then manually run `npx react-native start` in the example directory and reload the app.
