Have you used (tiling) window managers before?

If not, I would recommend to use other tiling window managers first. I started with awesome and then i3. After i3 became too opinionated for me (or I became too opinionated for i3), I switched to dwm because it's also from suckless like dmenu and I really like dmenu.

However, the config in C of dwm is definitely something that is quite unique among window managers. After every change, you have to recompile your window manager. But this sounds worse than it actually is in the long run. The hardest part is just to get comfortable with a configuration so you never have to touch it again, lol

But since you're working with C code, it's definitely intimidating and if you want to have some common features, you have to patch it yourself into your configuration file using patches other people provided.

I think I also almost ditched it because I couldn't figure out terminal scrolling, lol. But then I started to just use tmux as my default terminal which has scrolling built-in. And now I can't live without tmux: tmux + dmenu = <3

Not really. I had to make my own NixOS for dummies cheat sheet because the documentation confused the hell out of me. After playing around for a while, it turns out to be pretty logical. Keep in mind, I don't do anything very sophisticated. I learned the hard way to not mess with the configuration file much beyond your basic setup. I had to reinstall fresh more than once. Now I use home manager for messing around, and it's simpler to correct screwups. I really like how you can revert to prior configurations too. It's kind of idiot proof.
