How to install a gentoo Linux

This is a good question.I have test many distribution. I want to selected a good one.But until now ,I find the gentoo is the best one.I can selected what I need and installed just I needed.I don't liked to be given many programms that i may never used.I just need a clear system with just the programm i need.The gentoo give me.I like it.So I decided to just use gentoo to make my own desktop .
