A couple of things come to mind that I'm struggling with now: 1. how to install outside of NixOS, mostly to use home-manager, in a flake-y way using the new `nix profile` thing that supercedes nix-env. The few folks I've spoken to seem to prefer to use NixOS as a shell, then to manage their dotfiles with home-manager, and trying to figure out how to manage this global state in profiles with flakes (e.g. I've heard ~/.config/nixpkgs/flake.nix is the location, but hits on a web search for this file name are almost non-existent). 2. how does one _develop_ with flakes. I get confused about how to use the repl to add something into my config (thankfully there's :lf now!). Some simple walkthrough that goes from packaging a simple application and troubleshooting in the repl, using shell to check the build stages, etc, would be extremely useful. Once one gets over this hurdle, Nix becomes an extremely attractive tool to bundle existing code and manageg packages, and new users start to see the power of it.
