1. Use your Prospector to explore for valuable minerals.
2. Use your Engineer to build some railroad track from the capital city.
3. Look around the Terrain Map. Shift click on the map to get more information about it.
Most types of terrain on the map supply one type of resource. For instance, the orchard terrain supplies fruit, and the farm terrain supplies grain. Your civilian units work to expand the pool of available resources. You currently command two civilians, a Prospector and an Engineer.
To use map resources to feed your workers and supply your industries, you must connect them to a transport network. If a terrain tile is within one tile of a connected rail depot, a port, or the capital city, the resources in that tile are available to the transport network.
