How to use Poser

Since I had to reinstall windows awhile ago, most of the runtimes I had were deleted, its alright because I just use it for fun. I was using Daz Studio 3 but I think I will try Poser Pro now. Its installed fresh and I like to know how to install all the content. Where do I put it and how do I tell poser where to look for it. Looks like a nicer program then Daz but a lot more into it, which is a little confusing too. If any have a little knowledge of it and can explain how it can find my content , it would be great. I did google it but looks like I am not that smart to understand what they tell me.
