Important!
Some of these scripts may also rely on scripts created in previous episodes. Any updates to scripts will be shown below, but any scripts left unchanged would need to be sourced from the episode they were featured in. It is recommended to watch all videos in this series in order, that way you can piece together a working system with a good understanding of all the connected parts.
