There are instructions for setting up cockatrice included in the download. It's fairly straight forward, but if you run into any snags just visit the discord and another user will be happy to help you out!
There are plans for more infrastructure format in the works, like a scryfall or gatherer style website for the cardbase, and a discord bot. For now the way to browse the current format is through cockatrice itself. You can also view a simple image spoiler of every card that can rotate in each season here.
