Yes, garlic is planted in the fall. Plant it before the ground freezes; for me, I plant sometime between mid-October and Nov 1. (This is well after the first frost.) Put the cloves pointy end up, with the point about 2" below the surface of the soil. Then mulch thickly.
When the greens poke through the mulch in the spring, I pull the mulch back from around each plant so it can keep growing, unimpeded. I leave the mulch to keep the weeds down.
I get scapes in June, and dig the garlic bulbs when the bottom few leaves have turned brown. That's usually in July, so there is plenty of time to grow something else that will be ready in 60-70 days. I think I've planted zucchini in the garlic bed and gotten squash.
