-For example:
-
-1. Develop your code.
-1. Test your code.

-GitLab CI/CD is capable of not only testing or building your projects, but also
-deploying them in your infrastructure, with the added benefit of giving you a
-way to track your deployments. In other words, you always know what is
-currently being deployed or has been deployed on your servers.
-
-It's important to know that:
-
-- Environments are like tags for your CI jobs, describing where code gets deployed.
-- Deployments are created when [GitLab CI/CD](../yaml/README.md) is used to deploy versions of code to environments.
+Each time [GitLab CI/CD](../yaml/README.md) deploys a version of code to an environment,
+a deployment is created.
