Can you describe the main stages of continuous integration and delivery process?

The main stages of the Continuous Integration (CI) and Continuous Delivery (CD) process include:

1. Code Commit — developers regularly push changes to a shared repository.
2. Automated Build — the CI system automatically builds the project, verifying that changes do not break the build.
3. Automated Testing — unit tests and other types of tests are run to check code quality.
4. Code Quality Analysis — static analysis, style, and security checks.
5. Deployment to Testing Environments — automatic release to staging or testing servers for integration testing.
6. Manual or Automatic Approval — review and confirmation of readiness for release.
7. Deployment to Production — automatic or semi-automatic release to the live environment.

This approach allows for quick error detection, improved quality, and faster product delivery.
