A shipyard has several features. To access them, just hit ‘R’ (Activate/Open) on the shipyard, and press the “Place Order” Button. Here you can choose from several commands depending on the shipyard’s current state (e.g. if a ship is docked or not)
The Shipyard computer must be linked to both Shipyard Modules and exactly one Core Anchor to function. Link the computer and modules using C and V.
