As i love dracula theme, most of the files contains the config of dracula themes as it is. Alacritty, Zathura and Polybar are in dracula themes.
Clone:
git clone https://github.com/Unishkhadka/Dotfiles
After cloning this you can copy or move your desired folders to .config folder
For Rofi & polybar you can visit Aditya Shakya. But after moving the polybar make sure you add exec --no-startup-id bash ~/.config/polybar/launch.sh --forest
into your .config/i3/config
(or what you use).
