Usually, I just jump into my program of choice (we decided as a team what we would use for this project during project planning) and start blocking out how I want to chunk info, what kinds of interactions/practice activities I will need and do like a wireframe with notes. For some reason, I'm not making a lot of progress this way, so I think I'm going to get out a pen and actually draw.
I know there are a million different versions of storyboard templates out there in the world, but I've found keeping it simple usually works for me. I whipped this up a couple years ago when I started using Circa notebooks, so I could print out a bunch & punch it for my notebook to have on hand. I'm happy to share with you here :)
