 If you don't already have a Nerd Font installed (see https://www.nerdfonts.com/), I also highly recommend to do so, since it will greatly expand the amount of glyphs, icons and graphics that Nomad Network can use. Once you have your terminal set up with a Nerd Font, go to the `![ Config ]`! menu item and enable Nerd Fonts in the configuration instead of normal unicode glyphs.
