Guides for getting started?
(lemmy.world)
Submit screenshots of all your *NIX desktops, themes, and nifty configurations, or submit anything else that will make ricers happy. Maybe a server running on an Amiga, or a Thinkpad signed by Bjarne Stroustrup? Show the world how pretty your computer can be!
Look at somebody's setup, check the tooling they use to achieve it (e.g i3+Polybar or Sway+Waybar) and follow their respective tooling's first-setup guides / install guides
From there, familiarize yourself with the way they work and how to configure them.
From there, you're already on a good path.
Whenever you have questions, just ask! :)
