Understanding the process

I’m new to Scholars and still trying to work out the process between Thought Downloads (is it just a list of thoughts? on a specific thing or just here’s what i’m thinking right now?) and modeling. How do the downloads fit with Modeling? Do you download every day or just when you are facing a problem to solve? Do you choose one thought to model? or multiple? (which I assume is my choice to do). Once I’ve done a model on what i’m currently thinking then what? do i model a thought I would rather think? I attended the Model call but it didn’t really clarify it for me.
