I have previously mentioned that I would produce some videos to assist people in entering the lottery. Actually US DoS have produced an extremely good video and there is not much I can do to improve on what they have done. So – I am going to recommend you use their guide which is shown below. Prior to starting the entry you will want to prepare photos and I created a short video for that, so look at the official video first and then take a look at my introduction video for some hints on the photo tool.  I hope that helps!
