+### Continuous Delivery
 
-Continuous delivery is a series of practices designed to ensure that code can be rapidly and safely deployed to production by delivering every change to a production-like environment and ensuring business applications and services function as expected through rigorous automated testing.
+A [software engineering approach](https://about.gitlab.com/2016/08/05/continuous-integration-delivery-and-deployment-with-gitlab/) in which continuous integration, automated testing, and automated deployment capabilities allow software to be developed and deployed rapidly, reliably and repeatedly with minimal human intervention. Still, the deployment to production is defined strategically and triggered manually.
 
 ### Continuous Deployment
 
-Continuous deployment is the next step of continuous delivery: Every change that passes the automated tests is deployed to production automatically.
+A [software development practice](https://about.gitlab.com/2016/08/05/continuous-integration-delivery-and-deployment-with-gitlab/) in which every code change goes through the entire pipeline and is put into production automatically, resulting in many production deployments every day. It does everything that Continuous Delivery does, but the process is fully automated, there's no human intervention at all.
 
 ### Continuous Integration
 
-A process that involves adding new code commits to source code with the combined code being run on an automated test to ensure that the changes do not break the software.
+A [software development practice](https://about.gitlab.com/2016/08/05/continuous-integration-delivery-and-deployment-with-gitlab/) in which you build and test software every time a developer pushes code to the application, and it happens several times a day.
