@artdigital is on the money here. Our quick tip for beginners is to use `copilot-instructions.md` (which we can now generate for you <3), but for more serious use, we'd strongly recommend adding `copilot-setup-steps.yml`.

That gets you a deterministic setup - and for many teams, it'll be easy, as you can just copy and paste from existing Actions workflows.
