How-To on charging new A/C system

[dznucks]

I am about to install a CAA A/C system in my '69 this weekend. I have never owned a vehicle with A/C or messed with A/C before.
I have searched on the site for a How-To on charging a new system and I have googled it, but I didnt turn up anything that I thought gave good instructions.

Does anyone know of a good website or post on how to charge a new A/C system?

I have borrowed a vacuum pump and I have my dad's old A/C tool box that has gauges and various tools he used when working on A/C and refrigeration systems. I could go pay someone to do it, but I feel that defeats the purpose of the learning that comes from doing it myself.
