I will have a play with it later today; my greatest fear is that I break my website. I still sell courses from that website, and if I start changing things with vibe coding and AI, there is a chance that everything will stop working. I am ready and willing to revamp the site so that it is available for zaps on Nostr, but am I capable? My computer skills are awful, and even reading the tutorial that you have kindly made available makes me realize that I am pig-ignorant when it comes to coding. The following is from the very first image, and I have no idea what any of it means. It is all Greek to me.
Terminal
$ curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.40.3/install.sh | bash
$ \. "$HOME/.nvm/nvm.sh"
$ nvm install 22
$ node -v # Should print "v22.17.0".
$ nvm current # Should print "v22.17.0".
$ npm -v # Should print "10.9.2".
