This will get you started with everything the current emulator is capable of (which isn't much in the grand scheme of things).
Also, everyone asks the same questions and nobody reads the FAQs. So here's a thread of a lot of the same questions you're likely to ask, and I took time to answer them in detail. It also links to things like the FAQ and the getting started guide. Basically, the thread linked below will get you the most you can get out of the current emulator, and a general idea why the Unreal Engine 4 conversion is kind of stalled at the moment. Please take the time to read it, and welcome to the project!
