The conky script is a modified "now-clocking" script found here: https://www.omgubuntu.co.uk/2021/07/spotify-now-playing-conky-linux-widget

The neofetch thing with the icons is an idea of xfcisco, not mine. See here for the original file: https://github.com/xfcisco/BarricadesRice/blob/main/neofetch-config/config.conf

It support spotify and firefox (youtube), when nothing is playing it display basic system info (CPU,RAM...)

you can type

$ chmod +x setup.sh
$ ./setup.sh --all

that should install all the config file at the right place without deleting anything

You can also choose to install each part as you want:

$ ./setup zsh vim tmux

see ./setup --help for more info

it should work (not sure)

With popOS it give something that look like this:

OS : Pop! OS
DE : Gnome 40
Icons pack : BeautyLine (with candy-icons terminix svg for kitty)
Theme : Nordic-v40
Cursor : Nordzy-cursors
Spotify : spicetify plugin with dribbblish theme and beach-sunset color scheme
