Where do i put my hermit crab?

See, I'm a 16 y/o pet lover, and my group mates came to our house for an experimental baking and while we were stalling, one of my group mates who turns out to be a hermit crab lover saw my unused driftwood, which he badly wanted, since he was also my best friend, I gladly gave it to him, the next day , he gave me one of his hermit crab (land)..and I'm starting to get interested..so, how do I set up a tank or cage for it?
