+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`
+
+Example:
+```
+sda6_crypt UUID=9793d81a-4cfb-4712-85f3-c7a8d715112c none luks,discard,initramfs,keyscript=fido2luks
+```
+
+But don't forget to run `make install` which will install all necessary scripts and regenerate your intrid.
