-If you look at the image from the left to the right,
-you can see some of the features available in GitLab
-according to each stage (Verify, Package, Release).
-
-1. **Verify**:
-   - Automatically build and test your application with Continuous Integration.
-   - Analyze your source code quality with [GitLab Code Quality](../../user/project/merge_requests/code_quality.md).
-   - Determine the browser performance impact of code changes with [Browser Performance Testing](../../user/project/merge_requests/browser_performance_testing.md). **(PREMIUM)**
-   - Determine the server performance impact of code changes with [Load Performance Testing](../../user/project/merge_requests/load_performance_testing.md). **(PREMIUM)**
-   - Perform a series of tests, such as [Container Scanning](../../user/application_security/container_scanning/index.md) **(ULTIMATE)**, [Dependency Scanning](../../user/application_security/dependency_scanning/index.md) **(ULTIMATE)**, and [Unit tests](../unit_test_reports.md).
-   - Deploy your changes with [Review Apps](../review_apps/index.md) to preview the app changes on every branch.
-1. **Package**:
-   - Store Docker images with the [Container Registry](../../user/packages/container_registry/index.md).
-   - Store packages with the [Package Registry](../../user/packages/package_registry/index.md).
-1. **Release**:
-   - Continuous Deployment, automatically deploying your app to production.
-   - Continuous Delivery, manually click to deploy your app to production.
-   - Deploy static websites with [GitLab Pages](../../user/project/pages/index.md).
-   - Ship features to only a portion of your pods and let a percentage of your user base to visit the temporarily deployed feature with [Canary Deployments](../../user/project/canary_deployments.md).
-   - Deploy your features behind [Feature Flags](../../operations/feature_flags.md).
-   - Add release notes to any Git tag with [GitLab Releases](../../user/project/releases/index.md).
-   - View of the current health and status of each CI environment running on Kubernetes with [Deploy Boards](../../user/project/deploy_boards.md).
-   - Deploy your application to a production environment in a Kubernetes cluster with [Auto Deploy](../../topics/autodevops/stages.md#auto-deploy).
-
-With GitLab CI/CD you can also:
-
-- Easily set up your app's entire lifecycle with [Auto DevOps](../../topics/autodevops/index.md).
-- Deploy your app to different [environments](../environments/index.md).
-- Install your own [GitLab Runner](https://docs.gitlab.com/runner/).
-- [Schedule pipelines](../pipelines/schedules.md).
-- Check for app vulnerabilities with [Security Test reports](../../user/application_security/index.md). **(ULTIMATE)**
