+To use a FIDO2-Stick on [Linux-based systems](/wiki/linux.md) with
+[DM-Crypt](/wiki/linux/dm-crypt.md) first set up the FIDO2 stick and add it to the encrypted
+volume.

+It is recommended to set up [Plymouth]() so that the login screen is clean.
+Switch `udev` and other `HOOKS` to `systemd`.
+
+Next remove the UDEV-rules for usb-decryption in `FILES`.

 ## Setup
 
 TLP can be installed on most distributions by installing the `tlp` package.
+Additionally the installation of `tlp-rdw` is recommended, which is used to get better control over

 Afterwards the TLP
