 **What this does**: 
 - **Dynamic approach**: Downloads the latest stable Forgejo Actions runner
 - **Version pinning**: Allows you to specify a known-good version for production
-- **Makes the binary executable** and installs it system-wide for use by the SERVICE_USER
+- **System installation**: Installs the binary system-wide in `/usr/bin/` for proper Linux structure
+- **Makes the binary executable** and available system-wide
 
 **Production Recommendation**: Use version pinning in production environments to ensure consistency and avoid unexpected breaking changes.
