Place a Harvester on a wheat patch, run a Belt from it to a Mill, and keep going.
Quail Works
Raw patches feed machines, machines feed each other along belts, and a Depot turns finished crates into coin. Everything you place costs coin, so the first line you build pays for the second.

When a line backs up, that is the game telling you something downstream cannot keep up. You never need perfect ratios: drop a Router in the line and it will send the surplus sideways — into a second machine, or straight into a Depot to be sold.
