+# FCast Sender SDK
+
+## Required tools
+
+* [Rust](https://www.rust-lang.org/)
+* [Cargo](https://doc.rust-lang.org/cargo/)
+* [protoc](https://protobuf.dev/installation/)
+
+## Android
+
+### Additional required tools
+
+* [cargo-ndk](https://github.com/bbqsrc/cargo-ndk)
+* The `aarch64-linux-android`, `i686-linux-android`, `armv7-linux-androideabi` and `x86_64-linux-android` rustc targets
+  (can be installed with [rustup](https://rustup.rs/): `rustup target add x86_64-linux-android i686-linux-android armv7-linux-androideabi aarch64-linux-android`)
+* `JAVA_HOME` must point to a java implementation
+
+### Building
+
+To build the android library locally you first need to clone [fcast-sdk-jitpack](https://gitlab.futo.org/videostreaming/fcast-sdk-jitpack) locally, build the rust binaries and generate the UniFFI kotlin module:
+
+```console
+$ cargo xtask kotlin build-android-library --release --src-dir <path-to-fcast-sdk-jitpack>/src
+```
+
+Then follow the `Local testing` section [here](https://gitlab.futo.org/videostreaming/fcast-sdk-jitpack/-/blob/main/README.md?ref_type=heads).
+
+## IOS
+
+If `iphonesimulator SDK` is not found when running the build commands, execute the following:
+
+```console
+$ # xcode-select --switch /Applications/Xcode.app/Contents/Developer/
+```
+
+### Additional required tools
+
+* The `aarch64-apple-ios-sim` and `aarch64-apple-ios` rustc targets
+  (can be installed with [rustup](https://rustup.rs/): `rustup target add aarch64-apple-ios-sim aarch64-apple-ios`)
+
+### Building
+
+Execute:
+
+```console
+$ cargo xtask generate-ios
+```
+
+You can now import the SDK in your project by drag and dropping `ios-bindings/uniffi/{fcast_sender_sdk.swift, fcast_sender_sdkFFI.h}` and `ios-bindings/fcast_sender_sdk.xcframework` into Xcode.
