Click the character, then click the map to move. Press E to interact. Minimum earnings are 10 gold per day. You have 5 action points per day; moving will cost an action point. Unlocking resources and building buildings will cost one action point.

Resources can't generate gold by themselves; you need to connect them with the correct buildings(which double the resources), then connect to the Town Hall. But here is the trick: connecting building to building will have a similar effect as long as the resources output from the last building has similar resources, which means you can double the resource, then double it again and again until you connect to the Town Hall or a market. market can be placed in any building slot, and it will sell stuff at half price compared to the Town Hall.
