As much as neovim seems nice, I can't seem to find many resources to actually help start configuring neovim as a beginner. Help is very sparse, and the easiest thing seems to get a premade config, but then there are just too many features, and complexity gets in the way of understanding what's going on

I just started to get into neovim today, and I decided to follow the first tutorial I came across (neovim from scratch) on youtube. The first thing that's done is to copy the repo into .config/nvim/. At startup nvim set up a bunch of stuff. is there anything that it sets up outside of the ./config/nvim file? Because I really dislike installing stuff on my computer that just stays even after deleting the installation folder.

I'm relatively new to programming, I've been learning C on linux using nano and it's been very fun. I've recently fallen into the emacs/vim rabbithole and I've been watching videos about emacs, Doom, spacemacs, neovim and reading comments about people switching from this or that to another config or editor, and I've been a bit lost on what to do. Then I realised that I haven't done any coding and spent all of my time focusing on editors. So here is my question (which has probably been asked many times) : what is the point of investing so much time learning all of this when there are some IDEs that are preconfigured with all the functionality a programmer would need ? Does learning neovim or emacs actually save time in the long run? I know that they're much more lightweight than IDEs and I've been really enjoying using the terminal much more than my time on IntelliJ, but having an easy out of the box visual debugger, refactoring and jump into functions can be really helpful in the long run I think, especially when starting to write actual large programs. Nano is fun, but not a time saver. Why did you chose your editor?
