 # reHDD
 
-## Useful for:
+## Features:
-* checking new drives for the first time
+* show S.M.A.R.T values of attached drives
-* checking used drives for their next live
+* checking used drives for their next live based on threshold limits
+* delete a drive instant with wipefs
 * deleting a drive securely via overwriting
+* only needs a display and keyboard
+* process multiple drives at once
+
+## Download USB Image ##
+See reHDD-Bootable how the live image created: https://git.mosad.xyz/localhorst/reHDD-Bootable
+
+Use [Etcher](https://www.balena.io/etcher/#download) or `dd` to create an bootable USB drive .
