+## Installation Methods
+
+### Method 1: Go Install
+
+This method installs Go binaries directly from the repository.
+
+#### Main Binary Installation
+
+```bash
+# Set CGO_ENABLED=1 for tree-sitter support
+export CGO_ENABLED=1
+go install github.com/Anthony-Bible/codechunking/cmd/codechunking@latest
+```
+
+#### Client Binary Installation
+
+```bash
+# Client binary doesn't require CGO
+go install github.com/Anthony-Bible/codechunking/cmd/client@latest
+```
+
+#### Verify Installation
+
+```bash
+# Check main binary
+codechunking version
+
+# Check client binary
+codechunking-client version
+```
+
+#### Go Install Troubleshooting
+
+**Issue: CGO errors during installation**
+```bash
+# Ensure CGO is enabled
+export CGO_ENABLED=1
+
+# On Ubuntu/Debian, install build tools
+sudo apt-get update
+sudo apt-get install build-essential
+
+# On macOS, install Xcode tools
+xcode-select --install
+
+# On Windows, install TDM-GCC and add to PATH
+```
+
+**Issue: Module path not found**
+```bash
+# Ensure you're using Go 1.24+
+go version
+
+# Try with explicit version
+CGO_ENABLED=1 go install github.com/Anthony-Bible/codechunking/cmd/codechunking@v1.0.0
+```
+
+### Method 2: Pre-built Binaries
+
+Download pre-compiled binaries from GitHub releases for your platform.
+
+#### Finding Releases
+
+Visit: https://github.com/Anthony-Bible/codechunking/releases
+
+#### Downloading for Linux
+
+```bash
+# Determine your architecture
+ARCH=$(uname -m)
+case $ARCH in
+    x86_64) ARCH="amd64" ;;
+    aarch64) ARCH="arm64" ;;
+    *) echo "Unsupported architecture: $ARCH"; exit 1 ;;
+esac
+
+# Download latest version
+VERSION=$(curl -s https://api.github.com/repos/Anthony-Bible/codechunking/releases/latest | grep -o '"tag_name": "[^"]*' | cut -d'"' -f2)
+
+# Download main binary
+wget "https://github.com/Anthony-Bible/codechunking/releases/download/${VERSION}/codechunking-${ARCH}"
+chmod +x "codechunking-${ARCH}"
+sudo mv "codechunking-${ARCH}" /usr/local/bin/codechunking
+
+# Download client binary
+wget "https://github.com/Anthony-Bible/codechunking/releases/download/${VERSION}/client-${ARCH}"
+chmod +x "client-${ARCH}"
+sudo mv "client-${ARCH}" /usr/local/bin/codechunking-client
+```
+
+#### Downloading for macOS
+
+```bash
+# Using Homebrew (if available)
+brew install codechunking
+
+# Or manually download
+ARCH=$(uname -m)
+case $ARCH in
+    x86_64) ARCH="amd64" ;;
+    arm64) ARCH="arm64" ;;
+esac
+
+VERSION=$(curl -s https://api.github.com/repos/Anthony-Bible/codechunking/releases/latest | grep -o '"tag_name": "[^"]*' | cut -d'"' -f2)
+
+curl -L "https://github.com/Anthony-Bible/codechunking/releases/download/${VERSION}/codechunking-darwin-${ARCH}" -o codechunking
+chmod +x codechunking
+sudo mv codechunking /usr/local/bin/
+```
+
+#### Downloading for Windows
+
+```powershell
+# Using PowerShell
+$Version = (Invoke-RestMethod -Uri "https://api.github.com/repos/Anthony-Bible/codechunking/releases/latest").tag_name
+
+# Download main binary
+Invoke-WebRequest -Uri "https://github.com/Anthony-Bible/codechunking/releases/download/$Version/codechunking-windows-amd64.exe" -OutFile "codechunking.exe"
+# Download client binary
+Invoke-WebRequest -Uri "https://github.com/Anthony-Bible/codechunking/releases/download/$Version/client-windows-amd64.exe" -OutFile "codechunking-client.exe"
+
+# Add to PATH or move to desired location
+```
+
+#### Verifying Checksums
+
+Always verify downloaded binaries:
+
+```bash
+# Download checksums
+wget "https://github.com/Anthony-Bible/codechunking/releases/download/${VERSION}/checksums.txt"
+
+# Verify main binary
+sha256sum codechunking-${ARCH} | grep -f checksums.txt
+
+# Verify client binary
+sha256sum client-${ARCH} | grep -f checksums.txt
+```
+
+### Method 3: Build from Source
+
+Build binaries directly from source code.
+
+#### Quick Build
+
+```bash
+git clone https://github.com/Anthony-Bible/codechunking.git
+cd codechunking
+make build
+```
+
+The binaries will be created in `./bin/`:
+- `bin/codechunking` - Main application
+- `bin/client` - Client binary
+
+#### Detailed Build Instructions
+
+```bash
+# Clone repository
+git clone https://github.com/Anthony-Bible/codechunking.git
+cd codechunking
+
+# Install dependencies
+go mod download
+
+# Build with version
+./scripts/build.sh v1.0.0
+
+# Or cross-compile
+./scripts/build.sh --platform linux/amd64 v1.0.0
+```
+
+#### Build Script Options
+
+The build script (`scripts/build.sh`) supports multiple options:
+
+```bash
+# Show help
+./scripts/build.sh --help
+
+# Clean build
+./scripts/build.sh --clean v1.0.0
+
+# Verbose build
+./scripts/build.sh --verbose v1.0.0
+
+# Cross-platform builds
+./scripts/build.sh --platform linux/amd64 v1.0.0
+./scripts/build.sh --platform darwin/arm64 v1.0.0
+./scripts/build.sh --platform windows/amd64 v1.0.0
+
+# Build with test optimizations
+TEST_MODE=true ./scripts/build.sh v1.0.0
+```
+
+#### Make Commands
+
+```bash
+# Build both binaries (uses build script)
+make build
+
+# Build with specific version
+make build-with-version VERSION=v1.0.0
+
+# Build only main binary (legacy method)
+make build-main
+
+# Build only client binary (no CGO)
+make build-client
+
+# Install both binaries to GOPATH/bin
+make install
+
+# Install only client binary
+make install-client
+
+# Install development tools
+make install-tools
+
+# Clean build artifacts
+make clean
+```
+

+./scripts/build.sh --platform windows/amd64 v1.0.0
+
+# Environment variables for cross-compilation
+export GOOS=linux
+export GOARCH=arm64
+./scripts/build.sh v1.0.0
+```
+
+### Supported Platforms
+
+- **Linux**: amd64, arm64
+- **macOS**: amd64, arm64 (Apple Silicon)
+- **Windows**: amd64
+
+## Troubleshooting
+
+### Common Issues
+
+1. **Permission Denied**
+   ```bash
+   chmod +x codechunking
+   chmod +x codechunking-client
+   ```
+
+2. **Command Not Found**
+   ```bash
+   # Add to PATH
+   echo 'export PATH=$PATH:/usr/local/bin' >> ~/.bashrc
+   source ~/.bashrc
+   ```
+
+3. **CGO Errors**
+   ```bash
+   # Install CGO dependencies
+   # Ubuntu/Debian:
+   sudo apt-get install build-essential
+
+   # macOS:
+   xcode-select --install
+
+   # Windows:
+   # Install MinGW-w64 or TDM-GCC
+   ```
+
+4. **Tree-sitter Build Failures**
+   ```bash
+   # Ensure CGO is enabled
+   export CGO_ENABLED=1
+
+   # Clean build
+   ./scripts/build.sh --clean v1.0.0
+   ```
+
+5. **Version Information Missing**
+   ```bash
+   # Build with explicit version
+   ./scripts/build.sh v1.0.0
+
+   # Or let git describe determine version (recommended)
+   ./scripts/build.sh
+   # Uses: git describe --tags --always --dirty
+   ```
+
+6. **Cross-compilation Issues**
+   ```bash
+   # For Windows, need MinGW
+   sudo apt-get install gcc-mingw-w64-x86-64

 ## Installation
 
-### Using Go
+### Option 1: Go Install (Recommended for Development)
 
 ```bash
-go install github.com/Anthony-Bible/codechunking@latest
+# Install main binary (requires CGO_ENABLED=1 for tree-sitter)
+CGO_ENABLED=1 go install github.com/Anthony-Bible/codechunking/cmd/codechunking@latest
+
+# Install client binary only (lightweight, no CGO required)
+go install github.com/Anthony-Bible/codechunking/cmd/client@latest
 ```
 
-### Using Docker
+**Note**: The main binary requires CGO_ENABLED=1 due to tree-sitter dependencies. The client binary is standalone and doesn't require CGO.
+
+### Option 2: Download Pre-built Binaries
+
+Download pre-compiled binaries from GitHub releases:
 
 ```bash
-docker pull yourusername/codechunking:latest
+# Example for Linux amd64
+wget https://github.com/Anthony-Bible/codechunking/releases/latest/download/codechunking-v1.0.0
+chmod +x codechunking-v1.0.0
+sudo mv codechunking-v1.0.0 /usr/local/bin/codechunking
+
+# Client binary
+wget https://github.com/Anthony-Bible/codechunking/releases/latest/download/client-v1.0.0
+chmod +x client-v1.0.0
+sudo mv client-v1.0.0 /usr/local/bin/codechunking-client
 ```
 
-### From source
+Available platforms:
+- Linux (amd64, arm64)
+- macOS (amd64, arm64)
+- Windows (amd64)
+
+### Option 3: Build from Source
 
 ```bash

@@ -335,6 +356,45 @@ cd codechunking
 make build
 ```
 
+The build script creates two binaries in `./bin/`:
+- `codechunking` - Main application with tree-sitter support
+- `client` - Lightweight client binary
+
+### Option 4: Using Docker
+
+```bash
+docker pull ghcr.io/anthony-bible/codechunking:latest
+```
+
+### Version Verification
+
+Check installed version:
+
+```bash
+# Main binary
+codechunking version
+
+# Example output:
+CodeChunking CLI
+Version: v3.0.0
+Commit: abc123def456
+Built: 2024-06-01T12:00:00Z
+
+# Client binary
+codechunking-client version
+
+# Short version output
+codechunking version --short
+v1.0.0
+```
+
+### Binary Differences
+
+- **Main Binary (`codechunking`)**: Full-featured application including API server, worker, and file processing. Requires CGO for tree-sitter code parsing.
+- **Client Binary (`codechunking-client`)**: Lightweight standalone CLI for API interaction. No dependencies, ideal for CI/CD and AI agents.
+
+For detailed installation instructions and troubleshooting, see [INSTALL.md](INSTALL.md).
