+## Descripción general
+
+This app provides a directory, accessible via ssh of sftp, to a new user.
+
+A "chroot jail" limits the commands the user can use, so you can rest assured that
+they can't access your server's contents outside of the provided directory.
+
+A data size quota is also set on the directory.
