cd to the unzipped directory - there'll be files in caps such as README and INSTALL. Read those and do what they say. It's usually simply a sequence of commands:
but not always, so you need to read the docs to make sure about any particular details. Plus, with drivers, you'll need to find out about the 'mod' commands such as 'insmod' and 'lsmod' depending on how the drivers 'set themselves up', so to speak. So 'man lsmod' and such will get you started there.
If you have any trouble post back - I don't know how much I could help but somebody will.
