Yeah like I said, I struggled for a couple _years_ on having a feeling of complete confusion when copying a shell.nix to every project I spun up. I was never able to understand _any_ of the written documentation. After that playlist I easily click through the actual nixpkgs repo itself and find almost everything I need to handroll my own derivations.

It seems like the community is just a bunch of people who have had that lightbulb go on already, so its hard to go back and view things without the lightbulb on.
