+# SWC JNI Binding - Build Setup Guide
+
+This guide explains how to set up the build environment for SWC JNI bindings across multiple platforms.
+
+## 🚀 Quick Start
+
+### 1. Run the setup script
+
+```bash
+./setup.sh
+```
+
+### 2. Build all platforms
+
+```bash
+cd swc-jni && ./build.sh
+```
+
+## 📋 Prerequisites
+
+### Required Software
+
+- **Rust** (latest stable version)
+- **cargo-zigbuild** (for cross-compilation)
+- **Git** (for version control)
+
+### Platform-specific Requirements
+
+- **macOS**: Xcode Command Line Tools
+- **Linux**: Standard build tools (gcc, make)
+- **Windows**: No additional requirements (cross-compiled from any platform)
+
+## 🔧 Setup Script Features
+
+The `setup.sh` script automatically:
+
+1. **Verifies Rust installation**
+2. **Installs required Rust targets**:
+   - `x86_64-apple-darwin` (macOS Intel)
+   - `aarch64-apple-darwin` (macOS ARM64)
+   - `x86_64-unknown-linux-musl` (Linux x64 static)
+   - `aarch64-unknown-linux-gnu` (Linux ARM64)
+   - `x86_64-pc-windows-gnu` (Windows x64)
+   - `aarch64-pc-windows-gnullvm` (Windows ARM64)
+
+3. **Installs cargo-zigbuild** for cross-compilation
+4. **Verifies build environment**
+5. **Provides build configuration summary**
+
+## 🏗️ Build Configuration
+
+### Platform Support Matrix
+
+| Platform | Architecture | Toolchain | Directory | Static Linking |
+|----------|-------------|-----------|-----------|----------------|
+| **macOS** | Intel | Apple | `darwin-x64-apple` | No |
+| **macOS** | ARM64 | Apple | `darwin-arm64-apple` | No |
+| **Linux** | x64 | musl | `linux-x64-musl` | ✅ Yes |
+| **Linux** | ARM64 | GNU | `linux-arm64-gnu` | No |
+| **Windows** | x64 | GNU | `windows-x64-gnu` | No |
+| **Windows** | ARM64 | GNU | `windows-arm64-gnu` | No |
+
+### Toolchain Selection Rationale
+
+- **macOS**: Uses Apple native toolchain for optimal performance
+- **Linux x64**: Uses musl for static linking and better compatibility
+- **Linux ARM64**: Uses GNU toolchain (musl doesn't support cdylib)
+- **Windows**: Uses GNU toolchain for better cross-platform compatibility
+
+## 🛠️ Manual Setup (Alternative)
+
+If you prefer manual setup:
+
+### 1. Install Rust
+
+```bash
+curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
+source ~/.cargo/env
+```
+
+### 2. Install Rust targets
+
+```bash
+rustup target add x86_64-apple-darwin
+rustup target add aarch64-apple-darwin
+rustup target add x86_64-unknown-linux-musl
+rustup target add aarch64-unknown-linux-gnu
+rustup target add x86_64-pc-windows-gnu
+rustup target add aarch64-pc-windows-gnullvm
+```
+
+### 3. Install cargo-zigbuild
+
+```bash
+cargo install cargo-zigbuild
+```
+
+## 🧪 Testing the Setup
+
+### Test build (recommended)
+
+```bash
+./setup.sh --test-build
+```
+
+### Manual verification
+
+```bash
+cd swc-jni
+cargo check --target x86_64-apple-darwin
+cargo check --target aarch64-apple-darwin
+cargo check --target x86_64-unknown-linux-musl
+cargo check --target aarch64-unknown-linux-gnu
+cargo check --target x86_64-pc-windows-gnu
+cargo check --target aarch64-pc-windows-gnullvm
+```
+
+## 📁 Output Structure
+
+After successful build, libraries will be available in:
+
+```
+swc-binding/src/main/resources/
+├── darwin-x64-apple/
+│   └── libswc_jni.dylib
+├── darwin-arm64-apple/
+│   └── libswc_jni.dylib
+├── linux-x64-musl/
+│   └── libswc_jni.so
+├── linux-arm64-gnu/
+│   └── libswc_jni.so
+├── windows-x64-gnu/
+│   └── swc_jni.dll
+└── windows-arm64-gnu/
+    └── swc_jni.dll
+```
+
+## 🔍 Troubleshooting
+
+### Common Issues
+
+1. **Rust not found**
+
+   ```bash
+   # Install Rust
+   curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
+   source ~/.cargo/env
+   ```
+
+2. **cargo-zigbuild installation failed**
+
+   ```bash
+   # Try with specific version
+   cargo install cargo-zigbuild --version 0.18.0
+   ```
+
+3. **Target installation failed**
+
+   ```bash
+   # Update Rust first
+   rustup update
+   # Then retry target installation
+   rustup target add <target-name>
+   ```
+
+4. **Build fails with "cdylib not supported"**
+   - This is expected for `aarch64-unknown-linux-musl`
+   - The build script uses `aarch64-unknown-linux-gnu` instead
+
+### Environment Variables
+
+Optional environment variables for debugging:
+
+```bash
+export RUST_LOG=debug                    # Enable debug logging
+export CARGO_TARGET_DIR=custom_target    # Custom target directory
+export CC_aarch64_unknown_linux_gnu=zig  # Use zig as linker
+```
