Be sure to have Iosevka Nerd Font or any other Nerd Font for symbols.
If you're on Arch, you can simple run this and it will install all the stuff:
yay -S starship fastfetch grim slurp fish aylur-gtk-shell hyprland ttf-fantasquesansm-nerd swww papirus-icon-theme kitty fuzzel git base-devel
maybe there are some other dependencies like mpris, bluetooth, so if anything goes wrong, run this command too:
sudo pacman -Syu upower networkmanager pipewire-pulse libdbusmenu-gtk3 ttf-hanazono gvfs xdg-user-dirs
git clone https://github.com/larkjkj/dotfiles/
mv ~/dotfiles ~/.config/
Enjoy.
