Install and play.
It's a self contained game. You can enjoy everything about it without any prior knowledge.
If you're just interested in playing the games, then you'll be fine without reading anything.
For every "oh yeah, that place" or "oh yeah, that guy" moment you'll have, there's a "wait, that's not right" instance.
The books series is worth getting into though.
The game explains everything you need to know, plenty of text.
