City Council decided to cut down a 20 y/o tree in front of the shop i work at, and i got this slab as a memento, what is the process of turning this into chopping board?

Or at least, a side table. What is the process of doing that? I have basic hand tool for working on some other small project, a small circular saw(that attached to a marble cutter), and an electric planer, what else would i need?
