Editing Commercial Shipping v5.60 (section)

==Moving freight and colonists==
One colony must have a Supply contract for a certain good, another a Demand contract. You can set these in the tab of the Economics window. For example, to have the civilian ships move mines to Mars, add a supply of 50 mines on Earth and a demand of 50 on Mars. The civilian freighters will begin shipping mines to Mars now. The contract list will be updated to show how much goods are still waiting. You will be notified if a ship tries to pick up freight that is not available on the planet. If more than one colony has demand for a certain item, you cannot control which one is served first.

Colony ships (with either cryogenic chambers of passenger modules) will automatically pick up colonists and transport them to your colonies as long there is enough infrastructure to allow population growth.

* Private lines do not transport [[minerals]]. You have to take care of that yourself.
* They will only look for contracts within 4 jumps of a system.
* Although ships can land on any colony, you should consider building a [[Commercial Spaceport]] on high-traffic worlds to speed up loading and unloading.

See [[Civilian contracts]] for more details.
Also see [[Trade System]] for details on Civilian Trade Goods and how the civilian sector builds infrastructure.
