### Code of Conduct - [x] I have read and agree to the GitHub Docs project's [Code of Conduct](https://github.com/github/docs/blob/main/.github/CODE_OF_CONDUCT.md) ### What article on docs.github.com is affected? [Customizing the GitHub Copilot app](https://docs.github.com/en/copilot/how-tos/github-copilot-app/customize-github-copilot-app) ### What part(s) of the article would you like to see updated? Currently, the article only mentions instructions set up through the in-app UI. However, it seems to me all other GitHub Copilot products (CLI, VS Code, VS, etc.) make use of the `.github/copilot-instructions.md` file. That file is, however, not mentioned in the article above. I think one of two things are missing: 1. The article should mention/link to how `.github/copilot-instructions.md` is used and possibly how you can see proof that it's being used in a specific agent session (currently, I'm not sure how to confirm this). 2. If `.github/copilot-instructions.md` is not actually used when working from the GitHub Copilot app, then I would make a feature request for that (not sure which repo this belongs to). It's not intuitive that this file is ignored, and it's unclear how global instructions can be shared with a team working on the same repo (other than manually sending a copy to everyone). ### Additional information _No response_
