Localhost errors and bootstrap.php

[lonetour]

I am trying to learn php and "proper" dev practices (terminal, git, staging). My background is in no-code apps, but I have a solid knowledge of HTML and CSS. 

I started building a personal site on Neocities, very nice, but I realised that I needed a CMS. ProcessWire has been fabulous so far, while I've been creating files on my live hosting (LOL). 

I'm using Ai to help guide me through the "proper dev" practices, and honestly, it's been great. 

But now we're stuck. I'm trying to load my site locally. I've been getting various errors, blank screens. Ai insists that I need bootstrap.php and I need to get a fresh install of PW. When I look at the files in PW, there is no bootstrap.php. 

This page https://processwire.com/docs/front-end/include/ mentions bootstrapping, but no mention of the "missing" bootstrap.php file.

Any ideas?

ok... it seems that this is not the problem, and we've moved on.
