+Coding guidelines, which were previously deprecated, have now been removed as a way of customizing Copilot responses. You should now use Copilot custom instructions.

 In addition to repository-wide custom instructions, specified in the `.github/copilot-instructions.md` file, Copilot Code Review now supports:
 
 * Path-specific custom instructions, specified in `.github/instructions/NAME.instructions.md` files.
 * Custom instructions specified in the organization settings for Copilot.
 
 We have updated several articles in the GitHub documentation accordingly. We have also made changes to clarify the difference between the various types of custom instructions for Copilot Code Review, Copilot Chat, and Copilot Coding Agent.
 
-For example, see: [Adding repository custom instructions for GitHub Copilot](https://docs.github.com/en/copilot/how-tos/configure-custom-instructions/add-repository-instructions?tool=webui).
