Starting with reComputer J202

I recently purchased the Recomputer J202 along with the Jetson Nano module. As a newcomer to this type of board, I’m unsure about how to get started. I apologize in advance for any lack of understanding. Can someone please guide me through the start process? Thank you!

I’m sure this related wiki from SeeedStudio can get you started.
