first post - 03 civic gear shift removal/replace

Thanks for allowing me on your forum
I just would like to know how to remove the knob off my 5spd gear shift and replace it with one a friend gave me.
The instructions with the new knob are ambiguous, "remove knob - replace knob"
I don't know how to remove the stock knob.
Pls it'll mean the world for me.......................

usually they twist off like a bottle cap.
