 On SecureBoot enabled systems you will need additional steps for load this driver into the system. See [Signing](docs/SIGNING.md#signing) section.
 
 ### AUR package

 ### DKMS
 DKMS will install module into system, and will update it every time you update your kernel. Module will persist after reboots. It's the preferrable way to install it on the most distros.
