There are some other tutorials on this out there, but this is really comprehensive and backs it up with real world info and great explanations, so big thanks go to him for making this available. Also thanks to @Fengol (a “Producer at Luma Arcade, avid gamer, armchair political analyst and Masters student of Software Engineering” source: Twitter bio) who promoted this on Twitter.
