 ## Notice
-Even if we buid the kernel DKMS, one needs the following commands after new Kernel install.
-```
-$ sudo dkms autoinstall
-```
+If one has already the running dkms.service in systemd, the next reboot with new kernl image will make the kernel module be ready. However, if one doesn't have one, please run bash dkms/dkms_setup.bash in order to enable dkms.service.
 
-Or put dkms/dkms.service in your system dependent systemd service directory, and run
 ```
-$ sudo systemctl enable dkms.service
-$ sudo systemctrl start dkms.service
+$ bash dkms/dkms_setup.bash
