Are the any tutorials on how i can adjust/edit the envelopes for animation?
This will give you the basics of working with envelopes.

There’s not much else to it. How well envelopes will work for you depends a lot on the shape of your character. Skinny characters work pretty well with envelopes, usually, but in general envelopes aren’t nearly as flexible as weight painting.
I trying to use weight painting but nothing is happening. how do i use it? I went in to “weight paint” mode but thats it. how do i paint it?
Ok I think i got it! Have to use the RMB. Why can’t they make it a standard in using the LMB?
The weight painting itself is LMB for me. Not sure what’s happening there for you.
