Hello there, and welcome to Simcountry
First i recommend reading the documentation, which can be found in the top right of the menu bar. It's tedious and a little outdated in places but can give you the basic idea of how to play.
Meeting other players helps alot too - they can help you work out problems, and if you socialise enough on the forums and in chat, they may invite you into a federation. Federations protect and often teach you.
Hope you enjoy the game, Dub.
