-Type 'help' for available commands, or 'exit' to quit.
-Git-Mastery commands work with or without the 'gitmastery' prefix.
+Type '/help' for available commands, or '/exit' to quit.
+Use /command to run Git-Mastery commands (e.g. /verify), or 'gitmastery command'.
 Shell commands are also supported.
