Cool looking MOTD everyone seems to have

When looking at screenshots of other peoples nixos setups people often seem to have the same message of the day when opening a terminal. Examples include:

Screenshots shamelessly stolen from /r/unixporn



How do I get that exact message of the day?
Is it a module that I can enable?

That’s just neofetch. A shell script to display some information about your distro and system.

There are others like fastfetch or pfetch.

Just add the package and run the command.
