If so, a few seconds later it says “a default CLI project”. The CLI is introduced in lesson 1 step 4
It is one of those “once you know, you know” things - something so routine it can be taken for granted by an experienced developer, yet can be very confusing to a beginner when it’s assumed everyone will “know” and they don’t.
I have trouble with video lessons so I may be offering poor advice, but I think if you “watch” the intro steps without worrying about the details too much the blanks will fill in later.
