How to add modules to starbases

I must be stoopid !! I can't add any modules to my starbases. Do I have to research something in particular and what happens after that? Thanks.

You have to send a constructor to a star base and then you are asked whether you want to build an additional module (and which one).

Note: You need one constructor per module.

In addition to sending the constructor to the base you need to have researched the tech that unlocks various starbase upgrades.

And, for some upgrades, you need to spend a few blillion credits (unless you've managed to get to the point where you select an evil alignment, which gives you free upgrades).

I *heart* free upgrades. I'm not evil by nature, but that advantage has my alignment shifting quickly downward.
