Does the Constitution replace Copilot Instructions or can both be used?

[JLevy99]

I have been using Copilot Instructions to make sure certain restrictions and instructions for the AI are always followed, I have been working on creating a Copilot Instructions that can be shared between projects so the limitations are always in place. Should that set of instructions be part of the constitution and/or part of the .github\prompts\constitution.prompt.md?

I'm also trying to work this out. Wheres the overlap between copilot instructions and constitution.md. Could / should they mirror each other? Do they have different purposes?
