I never thought that the writing HTML is the hard part. Instead where my Sister struggled was to get a domain, get a server, deal with DNS pointing to that server. That shit is also omitted on posts like that one because it's done differently for each domain registrar and you need quite some knowledge in network stuff to be able to understand what you need to do.

This is an example where LLM's really can help. I just went through that process myself for the first time and got that help.
