+# Node-RED WebServices Project Guide
+
+## Build & Execution Commands
+- `npm install` - Install dependencies
+- `node-red` - Start Node-RED server
+- `node-red -v` - Get Node-RED version
+- `node-red --safe` - Run in safe mode
+- `node-red --flows flows.json` - Use specific flow file
+- `npm test` - Run all tests (when configured)
+
+## Code Style Guidelines
+- **Node-RED Flows**:
+  - Organize flows by functionality
+  - Use meaningful node names and labels
+  - Include descriptive comments on complex nodes
+  - Group related nodes using subflows
+- **Custom Nodes**:
+  - Follow Node-RED node development pattern
+  - Include proper node registration in package.json
+  - Use consistent error handling with status indicators
+  - Document node properties and behavior
+
+## Development Practices
+- Use environment variables for configuration
+- Keep credentials in separate flow_cred.json file
+- Implement proper error handling in function nodes
+- Test flows thoroughly before deployment
+- Create reusable subflows for common operations
+- Document API endpoints with OpenAPI/Swagger when possible
+
+## Authorship
+- Include author information in custom node files
