-# Workflows
-
-Replacing [Travis CI](https://travis-ci.org/) as this project's primary CI/CD tool,
-[GitHub Actions](https://help.github.com/en/actions) uses workflows to perform operations
-when specific events within the repository occur.
-Workflows are specified in YAML and can utilize shared components
-from other GitHub Actions to form expansive pipelines.
-
-These workflows should appear within pull requests as status indicators
-that denote "pending”, “success”, “failure”, or “error",
-and should contain detail links to view the workflows and their individual steps therein.
-Additionally, these workflow runs should be visible by clicking
-the [Actions](https://github.com/kshman/cactbot-build/actions) tab
-in the repository's menu at the top of the repository's main page.
