 ## Useful for:
 * checking new drives for the first time
 * checking used drives for their next live
-* deleting a drive securely
+* deleting a drive securely via overwriting

+![alt text](https://git.mosad.xyz/localhorst/reHDD/raw/commit/42bc26eac95429e20c0f0d59f684dfec0d600e75/doc/screenshot.png "Screenshot")
 
-* search for new attached Hard Drives via USB
+## Debian Build Notes
-* display Hard Drive Manufacturer, Model, Rotation Rate and Capacity
-* Check S.M.A.R.T. values and make an 'passed' or 'not passed' decision
-* If passed, wipe the data securely
 
+* `apt-get install ncurses-dev git make g++`
+* `make release`
+
+## Create Standalone with Debian 11
+
+Instructions how to create a standalone machine that boots directly to reHDD. This is aimed for production use, like several drives a day shredding.
+* Start reHDD after boot without login (as a tty1 shell)
+* Start dmesg after boot without login (as a tty2 shell)
+* Start htop after boot without login (as a tty3 shell)
+* Upload reHDD log every 12h if wanted
+
+### Software requirements
+* `apt-get install hwinfo smartmontools curl`
+
+
+### Installation
+
+clone this repo into /root/
+
+`cd /root/reHDD/`
+
+`make release`
+
+`bash scripts/install_reHDD.bash`
+
+If you want to upload the logs, edit `scripts/reHDDLogUploader.bash` with your nextcloud token
+
+Add your system drive in `/root/reHDD/ignoreDrives.conf` like:
+```e102f49d```
+Get the first 8 Bytes from your UUID via `blkid /dev/sdX`
+
+`reboot`
+
+## Build docs 
+`make docs`

-# Installation
-**[1]** In terminal als root einloggen\
-**[2]** In reHDD_prototype wechseln\
-**[3]** Abhängigkeiten installieren\
-`apt-get install smartmontools`\
-`apt-get install hwinfo`\
-`apt-get install util-linux`
-
-**[4]** reHDD ausführbar machen\
-`chmod +x reHDD`\
-**[5]** ignoreDrives.conf bearbeiten
-##### Ein Eintrag in der ignoreDrives-Datei sorgt dafür das die Software bestimmte Festplatten ignoriert. Dies ist wichtig damit nicht unbeabsichtigt die Systemfestplatte oder weitere Festplatten bearbeitet (gelöscht) werden.
-Beispiel Inhalt:
-```
-/dev/sda:508eff7d-f039-4efb-9e2c-22dffdfdfdfd
-/dev/sdb:07dfffff-c4b6-46e7-9cdf-3cfdfdffd53d
-/dev/sdc:dfff974d-1af2-4dfd-9dfd-a2d8e4c43dff
-```
-Ein Eintrag setzt sich aus zwei Teilen zusammen:
-
-**[Pfad]:[PARTUUID]**
-
-Der Pfad kann mittels `fdisk -l` ermittelt werden.\
-Die PARTUUID kann mittels `blkid /dev/sda` ermittelt werden, wobei `/dev/sda` derzuvor ermittelte Pfad ist.
- 
-# Benutzung
-reHDD starten mit `./reHDD`  (Wichtig ist das reHDD mit root-Rechen ausgeführt wird, entwender als root einloggen oder mit `sudo`)
-
-reHDD sucht automatisch nach allen verfügbaren Festplatten und filtert die zu ignorierenden heraus.\
-Für die verbleibenden Festplatten wird eine Übersicht ausgegeben. 
-Der Nutzer wird gefragt, welche Festplatte bearbeitet werden soll und gibt die Nummer ein.
-
-Beispiel:
-
-```
