Mecanim help

Hello. I've decided to use mecanim to manage my animations but I can't really find a good tutorial.
I've watched a bunch of tutorials on animator and animation scripts but still can't get my character to move.
The problem for me is that every tutorial I've seen starts in the middle - tutor already has created animator with transitions and the script is already written.

All I want to do is a simple idle -> walk state. Does anyone know any tutorials that starts from beggining on that matter? Or would someone be this kind to explain to me how to create a simple idle - walk animation with mecanim. I know how to set up animator, animation layers and transitions - I just can't make my character work.

 

I haven't watched this video in a while, but from my memory it goes through the entire process from setting up the character to creating state machine and blend trees including morph targets.

 

I'm gonna check it tommorow at work, thanks for help!
