 ### Disk Space Analyzer
 
-Use `--exclude-volumes` to skip external drives under `/Volumes` in the overview (faster when many volumes are attached).
+By default, overview skips external drives mounted under `/Volumes` for faster startup. To inspect external drives, run `mo analyze /Volumes` (or a specific mount path).

 $ mo analyze
