+# Docker Deployment Guide
+
+## Production Deployment
+
+### Quick Start
+```bash
+# Build and run the production container
+docker-compose up -d
+
+# Access the app at http://localhost:8080
+```
+
+### Manual Build
+```bash
+# Build the Docker image
+docker build -t coastal-timesheet .
+
+# Run the container
+docker run -d -p 8080:80 --name coastal-timesheet coastal-timesheet
+```
+
+## Development with Docker
+
+### Development Server
+```bash
+# Run development environment
+docker-compose -f docker-compose.dev.yml up
+
+# Access the app at http://localhost:5173
+```
+
+## Docker Commands
+
+### Production
+```bash
+# Start services
+docker-compose up -d
+
+# Stop services  
+docker-compose down
+
+# View logs
+docker-compose logs -f
+
+# Rebuild after changes
+docker-compose up -d --build
+```
+
+### Development
+```bash
+# Start dev environment
+docker-compose -f docker-compose.dev.yml up
+
+# Stop dev environment
+docker-compose -f docker-compose.dev.yml down
+
+# Rebuild dev container
+docker-compose -f docker-compose.dev.yml up --build
+```
+
+## Configuration
+
+### Environment Variables
+- `NODE_ENV`: Set to "production" for production builds
+- Port mapping can be changed in docker-compose.yml
+
+### Nginx Configuration
+The production container uses nginx to serve static files with:
+- Gzip compression enabled
+- Client-side routing support (SPA)
+- Static asset caching
+- Security headers
+
+### Ports
+- **Production**: http://localhost:8080
+- **Development**: http://localhost:5173
+
+## Architecture
+
+The production setup uses a multi-stage build:
+1. **Build stage**: Compiles the React app using Node.js
+2. **Production stage**: Serves static files using nginx
+
+This results in a lightweight production image (~25MB) that only contains the compiled app and nginx.
