I've heard of it, but...
I feel like it's missing something.
It's more accurate to say that it's a listed lecture, not an explanation of Docker Compose.
It's more like, "This is this", "If you do this, it will run."

I tried to summarize the main points, but I feel like it didn't help crimsonpinus much. I'll try harder.

Docker Compose always appears when you actually try to use Docker! You can learn what it is good for and how to use it through practice.
