+## CI/CD Pipeline
+
+The GitLab CI/CD pipeline automates building, testing, and deploying Orchard.
+
+### Pipeline Stages
+
+| Stage | Jobs | Description |
+|-------|------|-------------|
+| lint | `kics`, `hadolint`, `secrets` | Security and code quality scanning |
+| build | `build_image` | Build and push Docker image |
+| test | `python_tests`, `frontend_tests` | Run unit tests with coverage |
+| deploy | `deploy_stage`, `deploy_feature` | Deploy to Kubernetes |
+| deploy | `integration_test_*` | Post-deployment integration tests |
+
+### Environments
+
+| Environment | Branch | Namespace | URL |
+|-------------|--------|-----------|-----|
+| Stage | `main` | `orch-stage-namespace` | `orchard-stage.common.global.bsf.tools` |
+| Feature | `*` (non-main) | `orch-dev-namespace` | `orchard-{branch}.common.global.bsf.tools` |
+
+### Feature Branch Workflow
+
+1. Push a feature branch
+2. Pipeline builds, tests, and deploys to isolated environment
+3. Integration tests run against the deployed environment
+4. GitLab UI shows environment link for manual testing
+5. On merge to main, environment is automatically cleaned up
+6. Environments also auto-expire after 1 week if branch is not deleted
+
+### Manual Cleanup
+
+Feature environments can be manually cleaned up via:
+- GitLab UI: Environments → Stop environment
+- CLI: `helm uninstall orchard-{branch} -n orch-dev-namespace`
+
 ## Kubernetes Deployment
 
 ### Using Helm
 
 ```bash
-# Add Bitnami repo for dependencies
-helm repo add bitnami https://charts.bitnami.com/bitnami
-
-# Update dependencies
+# Update dependencies (uses internal OCI registry)
 cd helm/orchard
 helm dependency update
