 [Workers Builds](/workers/ci-cd/builds/) connects your Worker to a [Git repository](/workers/ci-cd/builds/git-integration/), and automates building and deploying your code on each pushed change.
 
-To make CI/CD pipelines even more flexible, Workers Builds now automatically injects [default system environment variables](/workers/ci-cd/builds/configuration/#environment-variable) into your build process (much like the defaults in [Cloudflare Pages projects](/pages/configuration/build-configuration/#environment-variables)). You can use these variables to customize your build process based on the deployment context, such as the branch or commit.
