+## 🔧 **Setup Instructions**
+
+### **1. Configure Repository Secrets**
+
+In your Gitea repository settings, add these secrets:
+
+```bash
+# Required
+GITEA_TOKEN          # For container registry access
+
+# Optional (for notifications)
+SLACK_WEBHOOK_URL    # Slack notifications
+STAGING_WEBHOOK_URL  # Staging deployment webhook
+PRODUCTION_WEBHOOK_URL # Production deployment webhook
+```
+
+### **2. Enable Actions**
+
+1. Go to your repository settings in Gitea
+2. Enable "Actions" if not already enabled
+3. Configure runners if using self-hosted runners
+
+### **3. Push to Repository**
+
+```bash
+# Initialize and push
+git init
+git remote add origin https://git.b4l.co.th/grabowski/Northern-Thailand-Ping-River-Monitor.git
+git add .
+git commit -m "Initial commit with Gitea Actions workflows"
+git push -u origin main
+```
+
+## 🎯 **Workflow Triggers**
+
+### **Automatic Triggers**
+- **Push to main/develop** → CI/CD Pipeline
+- **Pull Request to main** → Testing & Validation
+- **Daily at 2 AM UTC** → CI/CD Health Check
+- **Daily at 3 AM UTC** → Security Scanning
+- **Git Tag `v*.*.*`** → Release Pipeline
+- **Documentation Changes** → Documentation Build
+
+### **Manual Triggers**
+- **Manual Dispatch** → Any workflow can be triggered manually
+- **Release Creation** → Manual release with custom version
+
+## 📊 **Monitoring & Status**
+
+### **Status Badges**
+Your README now includes comprehensive status badges:
+- CI/CD Pipeline Status
+- Security Scan Status  
+- Documentation Build Status
+- Python Version Support
+- FastAPI Version
+- Docker Ready
+- License Information
+- Current Version
+
+### **Workflow Artifacts**
+Each workflow generates useful artifacts:
+- **Test Results** and coverage reports
+- **Security Scan Reports** (JSON format)
+- **Docker Images** (multi-architecture)
+- **Documentation** (HTML and PDF)
+- **Performance Reports**
+
+## 🚀 **Usage Examples**
+
+### **Development Workflow**
+```bash
+# Create feature branch
+git checkout -b feature/new-station-type
+# Make changes
+git add .
+git commit -m "Add support for new station type"

+make validate-workflows
+
+# Test workflow components
+make workflow-test
+
+# Run full test suite
+make test
+
+# Build Docker image
+make docker-build
+```
+
+## 📈 **Performance & Optimization**
+
+### **Caching Strategy**
+- **Pip dependencies** cached across runs
+- **Docker layers** cached for faster builds
+- **Workflow artifacts** retained for analysis
+
+### **Parallel Execution**
+- **Matrix builds** for multiple Python versions
+- **Independent jobs** for security and testing
+- **Conditional execution** to skip unnecessary steps
+
+### **Resource Management**
+- **Appropriate timeouts** prevent hanging workflows
+- **Artifact cleanup** manages storage usage
+- **Efficient Docker builds** with multi-stage approach
+
+## 🔒 **Security Best Practices**
+
+### **Implemented Security**
+- ✅ **Secret management** via Gitea repository secrets
+- ✅ **Multi-stage Docker builds** for minimal attack surface
+- ✅ **Non-root containers** for better security
+- ✅ **Vulnerability scanning** before deployment
+- ✅ **Dependency monitoring** with automated alerts
