After all the Garuda setup is over, we can start installing Hyprland using Hyde. You can check out the GitHub page for Hyde—installation instructions are available there.
But if you just want to copy-paste, here you go:
pacman -S --needed git base-devel
git clone --depth 1 https://github.com/HyDE-Project/HyDE ~/HyDE
cd ~/HyDE/Scripts
./install.sh
During the installation, it’ll ask you which themes to use for SDDM and GRUB. Pick whatever you like—I’ll be changing them later anyway.
Once Hyde finishes installing, reboot the system. At the login screen, make sure to select Hyprland and log in.
If your login fails even with the correct password (this happened to me), I’ve written how I fixed it here.
