Order of the videos

Okay so I can see that there are sections like “Getting Familiar”, “Built-in Movements”, “Specific Objects” ect… but my question is what order do we watch the videos? It says top to bottom, but in “Getting Familiar” you watch the first 2 videos and then on the third it states its the first video in the series. Either the videos should be labeled better like numbered or they should be arranged in order. The way the layout is now makes it confusing and honestly makes no sense.
