Gameplay Guide:

Upon entering the world, you will receive a Flight Starter Kit (also dropped by Ghasts). Combine the Flight Core (or any other block/item from the kit) with a Flight Engine in a crafting grid to create your Flyer.

All crafting recipes for this add-on (including Flight Engines and Upgrade Cores) can be viewed using mods like JEI.

Hold any Flyer in your hand and right-click to place it. Press W to mount and fly—the Flyer moves in the direction you are looking (look up to ascend, down to descend, etc.). Hold CTRL to boost your speed. Press SPACE to ascend vertically. Use the A/D keys to switch your riding animation.

You can use an Enchanting Table or an Enchanted Book to apply the Engine Mending enchantment to a Flyer. This automatically consumes your experience orbs to repair the engine's durability.
