+To build the package for the 6.10 kernel, pass KERNEL610 to the script.
+This is ONLY if you have built a 6.10/6.11 kernel for Slack 15.0.
+Also note that in this case the nvidia-drm module will NOT be built.
 
 BIG FAT NOTE: The Nvidia 390.xx series is EOL as of December 2022.
 Because of the ABI change from xorg-server 1.20 to 1.21, the Nvidia 390
