How did Miep Gies Elli Vossen Victor Kugler and Jo Koophuis help anne frank hide?

Because she wanted to help the Frank family and the other families that were with them in the "achterhuis".

She loved those people and tried everything to make it all a secret. But this unknown assh*le came up and heard about the secret somehow, told the Nazis and they came to the house to get these families and took them immediately to the concentration camp. It was a disaster. I've seen the movie and it explains it all, it shows you how everything went. >_<
