+# Docker Development Improvements - Contribution Summary
+
+This contribution adds comprehensive Docker development tools and documentation to improve the developer experience.
+
+## Files Added/Modified
+
+### 📚 Documentation
+- **`DOCKER_TROUBLESHOOTING.md`** - Comprehensive troubleshooting guide for common Docker issues
+- **`scripts/README.md`** - Documentation for helper scripts
+- **`README.md`** - Updated with Docker development section
+
+### 🛠️ Helper Scripts
+- **`scripts/docker-dev.sh`** - Linux/Mac Docker development helper script
+- **`scripts/docker-dev.bat`** - Windows Docker development helper script  
+- **`scripts/docker-health.sh`** - Quick health check script
+
+### ⚙️ Configuration Files
+- **`.dockerignore`** - Root-level Docker ignore file for optimized builds
+- **`docker-compose.dev.yml`** - Development-specific Docker Compose configuration
+
+## Key Features Added
+
+### 1. Comprehensive Troubleshooting Guide
+- Common Docker setup issues and solutions
+- Service-specific debugging commands
+- Performance optimization tips
+- Step-by-step problem resolution
+
+### 2. Development Helper Scripts
+**Cross-platform support** (Linux/Mac/Windows):
+- `setup` - Initial project setup with secret generation
+- `start/stop` - Service management
+- `restart/rebuild` - Individual service operations
+- `reset` - Complete environment reset
+- `status` - Health check with colored output
+- `logs` - Service log viewing
+- `db-reset` - Database reset functionality
+- `shell` - Container shell access
+
+### 3. Quick Health Monitoring
+- Automated service health checks
+- Visual status indicators
+- Quick access URLs display
+- Failure diagnostics
+
+### 4. Build Optimizations
+- Root `.dockerignore` for faster builds
+- Development-specific compose configuration
+- Hot reload setup for development
+
+## Developer Experience Improvements
+
+### Before
+- Manual Docker commands
+- No centralized troubleshooting
+- Repetitive setup tasks
+- Unclear error resolution
+
+### After
+- One-command setup: `./scripts/docker-dev.sh setup`
+- Comprehensive troubleshooting guide
+- Automated health checks
+- Cross-platform compatibility
+- Colored output for better UX
+
+## Usage Examples
+
+```bash
+# Quick setup
+./scripts/docker-dev.sh setup
+
+# Check everything is working
+./scripts/docker-health.sh
+
+# View backend logs
+./scripts/docker-dev.sh logs backend
+
+# Reset everything
+./scripts/docker-dev.sh reset
+
+# Get help
+./scripts/docker-dev.sh help
+```
+
+## Impact
+
+### For New Contributors
+- Faster onboarding with automated setup
+- Clear troubleshooting when issues arise
+- Reduced barrier to entry
+
+### For Existing Developers
+- Streamlined daily workflow
+- Less time debugging Docker issues
+- Consistent development environment
+
+### For Maintainers
+- Fewer Docker-related support requests
+- Standardized development setup
+- Better issue reporting with health checks
+
+## Testing Performed
+
+- ✅ Scripts work on Windows (batch files)
+- ✅ Scripts work on Linux/Mac (shell scripts)
+- ✅ All Docker operations function correctly
+- ✅ Health checks accurately report status
+- ✅ Troubleshooting guide covers real scenarios
+- ✅ Documentation is clear and actionable
+
+## Future Enhancements
+
+These contributions provide a solid foundation for:
+- CI/CD pipeline improvements
+- Additional development tools integration
+- Performance monitoring additions
+- Automated testing workflows
