[TYPO3-commerce] remove address selection on checkout - just have form for address

[Peter Waechtler]

hello,
saw that this can be done, but have no idea of where to start.
the user should do his shopping, then enter his address (every time)  
and send out the order.

changing only the template will not help, i think.

could you just give me a pointer or two?

thanks a lot.
