This is when all you hard work you have put in over the summer is about to be payed off. First of all if your growing outdoors you only have one choice pull the whole turn it upsidde down and let it dry. If it is at all possible you should try and dry you buds somewhere in the total darkness. Naturally do not micro wave it or your buds will taste like shit. Plus your microwave will smell like weed.
If your growing indoors you have a choice if you want you can chop the whole thing and plant again or you can harvest the top 3/4 of your plant and leave the bottom 1/4 under lights and in about 3-4 weeks you plant will start growing again. You must leave all the buds on the lower part that is left after you harvest.
