How do you make gluten-free bread?

My mum cannot eat food containing gluten. She has been trying to make gluten-free bread but the attempts made were not successful. She has tried doing it in a bread-maker with an online recipe (I don’t know which), but the dough failed to rise that much.

So do you know any tricks to getting the dough to rise? I also assume using a bread-maker for this task is a bad idea, or does it matter?

Any recipes will be helpful (if you KNOW they work).

Thanks.
