The “Catlearn” slug here identifies Open edX DevStack, a development environment for customizing Open edX. Use it to make one small course or platform change, run tests, and confirm a teammate can reproduce the setup from a clean checkout.
Do not treat a developer stack as a production hosting plan. Document how configuration and data move into a supported deployment workflow, and how upgrades are validated. The value is a repeatable development loop for Open edX changes.
