Continuous Deployment

Continuous deployment is the automated pipeline process spawned using GitHub Actions in order to deploy a production build of the code with a verified release tag, triggered by an event defined in the YML file. These actions are defined by you, the user, in the .github/workflows/continuous-deployment.yml file, which follows the GitHub Actions syntax.
