Bicycle Huffy

How do I adjust my 10 speed?
I have a huffy 10- speed bicycle. I need instructions on how to adjust it correctly so that I can change the speeds on my bicycle.
I have never known how,and would like to know how. I there are some websites or youtube please tell me thank you.
It is all in adjusting cable length and the appropriate screws on the derailleurs.
Since you wanted sites and not a lengthy description, here are the sites.

Read everything through before you attempt the first time. After that it is easy.
