I keep getting stuck on the first level of games -_- I'm so bad at this.

How do I get the quarrystone and marble to the lighthouse? What am I missing here? Do I just...get a carrier to drop it off at a warehouse right by it?

You need to send a merchant (carrier with enough experience can take profession of a merchant) to transfer needed materials from your warehouses to the warehouse next to the lighthouse (you need to build one close to the lighthouse). In manual is described how to set trade routes (in short select a merchant, select trade post 1 (main warehouse for example), select trade post 2 ("lighthouse" warehouse) and set type of goods you want to transfer between warehouses). I hope this help.

P.S. I apologize for my bad English.
