Although the Linux and Windows setups involve different methods, they are both logical, although it may not feel that way until you get a handle on where to look.

Putting Together the Pieces of the Puzzle

It helps to understand the lingo before getting started. A lot of this may be familiar to you from other operating systems such as Microsoft Windows, but you need to get used to some differences.
