-**💡 Important:** After installation, you may need to refresh your terminal or run `source ~/.zshrc` (or `~/.bashrc`) for the `kubectl oadp` command to work.
+**💡 Path Setup:** The installer will automatically check your PATH and guide you through any necessary setup. If `kubectl oadp` doesn't work immediately after installation, follow the on-screen instructions to update your PATH for the current session or restart your terminal.
 
 You can set the velero namespace afterwards using the oadp client command
