+## Build from Source
+
+### Prerequisites for Building
+
+* Go 1.20 or higher
+* Git
+* Make (for Linux/macOS builds)
+
+### Building on Linux/macOS
+
+1. Clone the repository:
+   ```bash
+   git clone https://github.com/wso2/open-mcp-auth-proxy
+   cd open-mcp-auth-proxy
+   ```
+
+2. Install dependencies:
+   ```bash
+   go get -v -t -d ./...
+   ```
+
+3. Build for your platform:
+   ```bash
+   # Build for all platforms
+   make all
+   
+   # Or build for a specific platform
+   make build-linux   # For Linux
+   make build-darwin  # For macOS
+   make build-linux-arm # For ARM-based Linux
+   make build-windows # For Windows
+   ```
+
+4. Find your build in the `build` directory:
+   ```bash
+   # For Linux
+   ./build/linux/openmcpauthproxy --demo
+   
+   # For macOS
+   ./build/darwin/openmcpauthproxy --demo
+   ```
+
+### Building on Windows
+
+1. Clone the repository:
+   ```powershell
+   git clone https://github.com/wso2/open-mcp-auth-proxy
+   cd open-mcp-auth-proxy
+   ```
+
+2. Install dependencies:
+   ```powershell
+   go get -v -t -d ./...
+   ```
+
+3. Option 1: Build using Make if you have it installed:
+   ```powershell
+   make build-windows
+   ```
+
+   Option 2: Build manually without Make:
+   ```powershell
+   mkdir -p build\windows
+   go build -o build\windows\openmcpauthproxy.exe .\cmd\proxy
+   copy config.yaml build\windows\
+   ```
+
+4. Run the built application:
+   ```powershell
+   cd build\windows
+   .\openmcpauthproxy.exe --demo
+   ```
+
+### Starting the Proxy on Windows
+
+1. Open Command Prompt or PowerShell
+2. Navigate to the build directory:
+   ```powershell
+   cd build\windows
+   ```
+
+3. Run the executable with your desired options:
+   ```powershell
+   # Start in demo mode (using Asgardeo sandbox)
+   openmcpauthproxy.exe --demo
+   
+   # Start with Asgardeo integration
+   openmcpauthproxy.exe --asgardeo
+   
+   # Start in stdio mode
+   openmcpauthproxy.exe --demo --stdio
+   
+   # Enable debug logging
+   openmcpauthproxy.exe --demo --debug
+   
+   # See all available options
+   openmcpauthproxy.exe --help
+   ```
+
+4. The proxy will start and display messages indicating it's running
+5. To stop the proxy, press `Ctrl+C` in the command window
