Customizing the 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).
