 Flutter package that bind [dubp-rs-libs] Rust crates.
 
+## Setup
+
+### Prerequisites
+
+* Android SDK
+* Android NDK
+* Rust and cargo
+* Cargo plugin cargo-make: `cargo install cargo-make`
+* LLVM/Clang (see dedicated section below)
+
+You will also need to add targets for all Android architectures:
+
+```sh
+rustup target add aarch64-linux-android armv7-linux-androideabi x86_64-linux-android i686-linux-android
+```
+
+If you develop on mac, you can also add targets for iOS:
+
+```sh
+rustup target add aarch64-apple-ios x86_64-apple-ios
+```
+
+### LLVM/Clang
+
+The project use [`dart-bindgen`](https://github.com/sunshine-protocol/dart-bindgen) which requires LLVM/Clang. Install LLVM (10+) in the following way:
+
+#### ubuntu/linux
+
+1. Install libclangdev - `sudo apt-get install libclang-dev`.
+
+#### Windows
+
+1. Install Visual Studio with C++ development support.
+2. Install [LLVM](https://releases.llvm.org/download.html) or `winget install -e --id LLVM.LLVM`.
+
+#### MacOS
+
+1. Install Xcode.
+2. Install LLVM - `brew install llvm`.
+
+## Compile
+
+### For development
+
+**To reduce the compilation time of the Rust code** during your development, you can **compile only for the target corresponding to your android emulator**. Here is how to do it **depending on the architecture of your emulator**:
+
+* 32bit emulator (`x86`/`i686` architecture)
+
+```sh
+cargo make android-dev32
+```
+
+* 64bit emulator (`x86_64` architecture)
+
+```sh
+cargo make android-dev
+```
+
+### For release
+
+In the Root of the project simply run:
+
+```sh
+cargo make
+```
+
+WARNING: This will take a lot of time because the Rust code will have to be recompiled for each different architecture, 4 times for android and 2 times for iOS!
