A method I used when first getting used to the movement, read it somewhere.
Took the bike and a crate to the back yard. Then saw on seat with one foot on crate. Other foot clipped in and out of over and over, then switched feet. Helps you learn where on the foot the cleat is and the general motion ot get into and out of the pedal.

Good luck It is worth it. And you will fall, it is just a matter of time Still worth it though.
