About Copilot instructions

What is copilot-instructions.md?

Repository-wide instructions for GitHub Copilot, kept in .github/copilot-instructions.md.

What should it contain?

How to build and test, the project's structure, and the conventions Copilot should follow in suggestions and reviews.

Does it replace AGENTS.md?

No. Copilot's coding agent also reads AGENTS.md, so many projects keep the shared rules there.
