 ## Initramfs-tools based systems(Ubuntu and derivatives)
 
-After installation generate your credentials and add keys to your disk as described in the top-level README
-then add `initramfs,keyscript=fido2luks` to your `/etc/crypttab`
+For easiest installation [download and install the precompiled deb from releases.](https://github.com/shimunn/fido2luks/releases). However it is possible to build from source via the instructions on the main readme.
 
-Example:
 ```
-sda6_crypt UUID=9793d81a-4cfb-4712-85f3-c7a8d715112c none luks,discard,initramfs,keyscript=fido2luks
+sudo -s
+
+# Insert FIDO key.
+fido2luks credential
+# Tap FIDO key
+# Copy returned string <CREDENTIAL>
+
+nano /etc/fido2luks.conf
+# Insert <CREDENTIAL> 
+# FIDO2LUKS_CREDENTIAL_ID=<CREDENTIAL> 
+
+set -a
+. /etc/fido2luks.conf
+fido2luks -i add-key /dev/<LUKS PARTITION>
+# Current password: <Any current LUKS password>
+# Password: <Password used as FIDO challange>
+# Tap FIDO key
+
+nano /etc/crypttab
+# Append to end ",discard,initramfs,keyscript=fido2luks"
+# E.g. sda6_crypt UUID=XXXXXXXXXX none luks,discard,initramfs,keyscript=fido2luks
+
+update-initramfs -u
+
+
 ```
 
-But don't forget to run `make install` which will install all necessary scripts and regenerate your intrid.
