     your mounted volumes with permissions matching your host filesystem.
-- Mount volumes in user's home folder.
+  - Add directory names at the end, if you want to create them and/or set user
+    owership. Perfect when you just want a fast way to upload something without
+    mounting any directories, or you want to make sure a directory is owned by
+    a user.
+- Mount volumes in user's home direcotry.
   - The users are chrooted to their home directory, so you must mount the
     volumes in separate directories inside the user's home directory
     (/home/user/**mounted-directory**).
