To use this you need fastfetch, it's not neofetch but it's better and maintained. I may make a neofetch version soon.
To install simply place the config.jsonc into your fastfetch directory at /home/.config/fastfetch (on Linux), and customize it to your heart's desire if you feel like it.
All you need is the config.jsonc indeed but I also added ULTRAKILL's font (VCR OSD) if you wanna use it in your terminal and the V1 ASCII art.
