 ### Setup
 
 ```bash
-brew install gitleaks   # one-time install
-./setup-hooks.sh        # installs the pre-commit hook
+# macOS / Linuxbrew
+brew install gitleaks
+
+# Debian/Ubuntu (download binary)
+curl -sSL https://github.com/gitleaks/gitleaks/releases/latest/download/gitleaks_$(uname -s)_$(uname -m).tar.gz | sudo tar -xz -C /usr/local/bin gitleaks
 ```
 
 The hook runs automatically on every `git commit`. If gitleaks isn't installed, the hook prints a warning and allows the commit (no hard dependency on collaborators).
