+# Agoo C - Production-Grade Web Server
+
+This is a production-optimized implementation of the Agoo C web framework with security best practices, disabled debug logging, and enhanced readability.
+
+## Features
+
+- **Security Hardened**: Disabled debug logging, added input validation, request size limits
+- **Production Optimized**: Maximum performance with security flags, PIE/ASLR support
+- **Readable Code**: Well-documented, consistent formatting, comprehensive error handling
+- **Best Practices**: Security headers, proper resource cleanup, validated inputs
+
+## Security Features
+
+### Application-Level Security
+- **Input Validation**: All user inputs are validated for length and format
+- **Request Size Limits**: Maximum request size of 10MB to prevent DoS attacks
+- **Error Handling**: Comprehensive error checking with proper error responses
+- **Security Headers**: Standard security headers configured (when supported by framework)
+- **Debug Disabled**: Debug logging disabled in production mode
+
+### Build-Level Security
+- **Stack Protection**: `-fstack-protector-strong` enabled
+- **Fortify Source**: `-D_FORTIFY_SOURCE=2` for additional buffer overflow protection
+- **Position Independent Executable**: ASLR support via PIE
+- **Strip Debug Symbols**: Production builds have debug symbols removed
+
+## Building
+
+### Production Build (Recommended)
+```bash
+make production
+```
+
+This creates an optimized, stripped binary with all security features enabled.
+
+### Development Build
+```bash
+make develop
+```
+
+This creates a debug build with symbols for debugging and development.
+
+### Standard Build
+```bash
+make
+```
+
+Creates a production build (same as `make production`).
+
+## Build Options
+
+The Makefile includes the following optimization and security flags:
+
+- **Optimization**: `-O3 -march=native -mtune=native`
+- **Warnings**: `-Wall -Wextra -Wpedantic -Wshadow -Wconversion -Werror`
+- **Security**: `-D_FORTIFY_SOURCE=2 -fstack-protector-strong -fPIE`
+- **Linking**: `-pie -s` (Position Independent Executable + stripped symbols)
+
+## Running
+
+Start the server:
+```bash
+./simple
+```
+
+The server will listen on port 3000 by default.
+
+## Endpoints
+
+- `GET /` - Returns 200 OK
+- `GET /user/*` - Returns the user ID from the URL path
+- `POST /user` - Returns 200 OK
+
+## Configuration
+
+### Server Configuration
+- **Port**: 3000 (configure in `main()` function)
+- **IO Thread Ratio**: 1.0 (optimized for multi-core systems)
+- **Poll Wait**: 0.01 seconds (10ms)
+- **Eval Threads**: 1 (sufficient for most use cases)
+- **Max Request Size**: 10MB (configurable via `MAX_REQUEST_SIZE`)
+
+### Log Level
+Production builds use `AGOO_LOG_ERROR` to only log errors. For development, you can change this to:
+- `AGOO_LOG_DEBUG` - All debug messages
+- `AGOO_LOG_INFO` - Informational messages
+- `AGOO_LOG_WARN` - Warnings only
+- `AGOO_LOG_ERROR` - Errors only (production default)
+
+## Security Best Practices Implemented
+
+1. **Input Validation**: All user inputs validated before processing
+2. **Buffer Overflow Prevention**: Length checks on all string operations
+3. **Resource Limits**: Maximum request size enforced
+4. **Error Handling**: Proper error codes and cleanup
+5. **Secure Defaults**: Debug disabled, minimal information disclosure
+6. **Build Security**: Hardened compilation flags and options
+
+## Development Workflow
+
+1. **Debug Build**: Use `make develop` for debugging
+2. **Production Build**: Use `make production` for deployment
+3. **Testing**: Use `make test` to run the server
+4. **Cleanup**: Use `make clean` to remove build artifacts
+5. **Rebuild**: Use `make rebuild` for clean rebuild
+
+## Docker Usage
+
+Build and run in Docker:
+```bash
+docker build -t agoo-c-app .
+docker run -p 3000:3000 agoo-c-app
+```
+
+The Dockerfile includes additional security hardening:
+- Non-root user execution
+- Clean package caches
+- Health checks configured
+
+## Performance Tuning
+
+Adjust the following parameters based on your hardware:
+- `agoo_io_loop_ratio`: Ratio of IO threads to processors (1.0 recommended)
+- `agoo_poll_wait`: Poll wait time in seconds (0.01 = 10ms)
+- `agoo_server.thread_cnt`: Number of evaluation threads
+- `MAX_REQUEST_SIZE`: Maximum allowed request size
+
+## Contributing
+
+When making changes, please:
+1. Maintain the existing code style and formatting
+2. Add comprehensive comments for complex logic
+3. Include input validation for all user inputs
+4. Handle errors appropriately
+5. Test both development and production builds
