Please, Zcarfaz, take the time to ask your favorite internet search engine at first. You will find thousands of matching answers, which have been published already.

The forum is not the right location to learn the very basics. Note that the users are all volunteers who spend their spare time. The basics are explained exhaustively in the "Getting Started" cahpters of the documentation. It would not be efficient to rephrase these excellent docs.
