@olayway since you have done this, can you briefly describe the steps here ?

[olayway]

@khalilcodes I'm just using degit like with other upgrades before. It's hard for me to list all the diffs that should be reconciled this or that way off the top of my head. Please give it a go, create a PR and I'll take a look. You can also ping me on discord.
If you're really not sure how to do this and you have some other stuff to work on, I can do it myself tomorrow.
