If you’ve never used Actions before, I highly recommend you have a quick read of that before reading this, as I build on some of the ideas presented there. Continuous Integration (CI) versus Continues Deployment (CD) versus Continuous Delivery (unhelpfully, also CD) Put simply, continuous integration is the act of continually moving your changeset into the wider codebase, as frequently as it makes sense for your use case....

A full solution for continuous delivery tends to include (but isn’t limited to): The ability to create artefacts that we can release to production, across many products, teams, branches, environments and repositories.
