+# GitHub Actions Workflows
+
+## Angular CI Pipeline
+
+### Triggers
+- **Push**: Runs on all branches when changes are made to `ui/` folder
+- **Pull Request**: Runs when PR targets `main` branch
+
+### Pipeline Stages
+
+1. **Checkout** - Clone repository
+2. **Setup Node.js** - Install Node 20.x with npm cache
+3. **Install Dependencies** - Run `npm ci`
+4. **Type Check** - Run `npx tsc --noEmit`
+5. **Lint** - Run `npm run lint`
+6. **Format Check** - Run `npm run format:check`
+7. **Build Dev** - Build development configuration
+8. **Build Prod** - Build production configuration
+9. **Test** - Run unit tests with coverage
+10. **Upload Artifacts** - Save build outputs and coverage reports
+
+
+### Local Testing
+
+Before pushing, run locally:
+```bash
+cd ui
+npm ci
+npx tsc --noEmit
+npm run lint
+npm run format:check
+npm run build
+```
+
+### Troubleshooting
+
+**Node version mismatch:**
+```bash
+# Use Node 20.x locally
+nvm use 20
+```
+
+**Cache issues:**
+```bash
+# Clear npm cache
+npm cache clean --force
+rm -rf node_modules package-lock.json
+npm install
+```
+
+**Lint errors:**
+```bash
+# Auto-fix
+npm run lint -- --fix
+```
+
+**Format errors:**
+```bash
+# Auto-format
+npm run format
+```
