Full disassembly + assembly of the X-Plus 3 extruder (or head, IDK what it's called) guide/video?

Hi, all

I tried to replace the hotend for my X-Plus 3 so I removed lots of screwes, not knowing how to do it (first printer, couldn't find a guide), and only after I was able to do it found a simple video by QiDi on how to do it, and am left with various screws (and a bit of parts) and I don't know where they're supposed to go.
Is there a full guide on how to completel disassemble and assemble the whole head? I want to make sure I don't miss putting back any screws.
