It measures Revolution Per MInute (RPM). This is important in performance cars or hard working motors to keep them from overreving which can cause engine damage. On an everyday car they are used very little.

How do you install a tach?

This entirely depends on the vehicle and the type of tach your referring to such as a add on tach or an OEM in dash tach. To explain how to install and OEM tach would take far to long. I would suggest a add on tach that mounts basically where ever you want to mount it. Most of these tachs explain the installation instructions. I personally recommend a tach by Autometer you can view their products on the web at the link below. , EzForJesus http://www.autometer.com/

How do you put in a tach if your vehicle doesn't come stock with one?

there will be a spot on back of distributor cap it will say tach run wire from there to gauge. You probably need to run a switched 12v lead as well to illuminate the tach at night. The tach slot on the distributor will take care of 'timing' the pulse to the tach. Often times the tach will have a switch setting for 4-6-8 cylinder. Read the manufacturer instructions carefully.
