The tutorial should essentially be similar to Svelte/Kit one but as interactive as possible, and as ludic as possible, making it as fun and accessible as possible for many levels of comprehension.
The chapters and setps should be interactive and simulate machines, applications and etc in realtime Also should show interfaces that are distinct for each part of them, making clear when something is local, remote, etc
Also show essential statistics like ping, requests/responses counts, a graph(or more, grahps good), etc
Load compilers(in WASM i think?) that allow for compilation of code of the tutorial in realtime
Display a page warning the progress of the download while it happens, speed, ETA, etc.
