X4 - Now with more flyable ships

Woo I got a station! With an asteroid in the middle. But I’m a bit perplexed about supplying the build with resources. I found myself a builder and he’s there, but it doesn’t have anything. Am I supposed to go from station to station manually buying them myself and dropping them off? If so, is there a way to see materials needed when I’m at the checkout counter? Or am I supposed to buy and deliver them, or have them delivered?

I’m at a loss here, but excited!
