1. Pick Miner and tap an ore patch. Miners only work on ore.
2. Pick Conveyor and drag a line from the miner to the Depot. Everything that reaches the Depot is shipped and scores.
3. Furnaces smelt ore into ingots but burn coal — feed them both on the same belt, or on two belts.
4. Assemblers take up to three ingredients. Pick their recipe by tapping them.
5. Belts have a carrying limit. When one backs up, widen the line, split it, or upgrade the belt.
