build buildings....?
At any one time, you can be constructing a building, researching something (once you have an Alchemy Lab), building defenses (click on your wall) and training a troop (once you have a barracks).
Click on an empty plot in the City or Field (see tabs at top left) to select what you want to build.
Click on Wall in your city to build defenses (or upgrade your wall).
Click on your Alchemy Lab to research.
Click on your barracks to train troops.
You can queue up as many troops as your number of barracks.
