 ### Steps to create
-- `cd /usr/src/`
-- `wget https://git.arrr.cloud/whichdoc/plague-kernel/-/raw/main/5.10-hardened.config -o linux-hardened-"$KVER"/.config`
-- `/usr/bin/curl --verbose --tlsv1.3 --proto =https -L -O --url "https://github.com/anthraxx/linux-hardened/archive/refs/tags/5.10."$KVER"-hardened1.tar.gz"`
-- `tar -xvf 5.10."$KVER"-hardened1.tar.gz`
-- `cd 5.10."$KVER"-hardened1`
-- `make oldconfig`
-- `make menuconfig` # (if any changes are required)
-- `make --jobs=4` # start compiling with your number of allocated threads
-- `make modules_install` # create /lib/modules/$kver
-- `cp ./arch/x86_64/boot/bzImage /boot/vmlinuz-5.10."$KVER"-hardened1_1 && dracut --kver 5.10."$KVER"-hardened1_1 --force`
-- `grub-mkconfig -o /boot/grub/grub.cfg`
-- `xbps-reconfigure -fa`
+1. Set the KVER variable to which version you want to obtain from Anthraxx's linux-hardened repository
