step 1: click this link Snap! Build Your Own Blocks its not advertising, the project is literally the editor
step 2: click edit
step 3 use this category, its important, without it, it isnt a scrape project (extensions like bbq-binary are optional to add)
step 4: make something out of it like a normal snap project
step 5: after finishing, publish it and mark it as a remix of this project: Snap! Build Your Own Blocks this still isnt advertising
this will be updated, if a new version comes around
