I understand that you want to get your site up and running as fast as possible. But if you are a newbee in this kind of stuff (like myself), you need to take your time and carefully read and follow instructions.
And although instructions are often written in a very step by step manner (thank you to all tutorial writers ) I suggest you also try to understand (at a basic level) what you are actually doing in each step. That takes a bit longer but will safe you time and hassle in the long run, because you gradually get knowledgeable in what you’re doing.
