Prismatic Wings adds two upgrades to the elytra: Constellation and Terminal Velocity.

To make Constellation, bring an elytra, nether star, and an echo shard to a smithing table: Press shift while flying with Constellation for a huge boost forward; press A or D to strafe left or right.

To make Terminal Velocity, bring and elytra, nether star, and a heavy core to a smithing table: Look downward toward the ground (within 50 degrees of straight down) while flying with Terminal Velocity to gain Nitro. Hold shift to spend Nitro for constant, powerful thrust. Looking straight down triples Nitro gain, but risks slamming into the ground.

Here's a short demo showing how everything works:
