 ## Install with Homebrew
 
 ```bash
-brew tap TZGyn/tap
-brew trust TZGyn/tap          # Homebrew 6+ requires trusting third-party taps
+brew tap TZGyn/tap https://gitea.tzgyn.dev/TZGyn/homebrew-tap.git
 brew install --cask kapture
 ```
 
+The tap is hosted on Gitea, so the full URL is required. Homebrew may print
+an "Unsupported tap" warning — it's harmless.

 Releases are published as zips on GitHub Releases; `release.sh` packages a
 new one (`./release.sh 1.0.1 && git tag v1.0.1 && git push origin v1.0.1`).
 The cask lives in the [TZGyn/homebrew-tap](https://github.com/TZGyn/homebrew-tap)
