Tips for starting a garden from scratch?

Tips for starting a garden from scratch?

My girlfriend and I recently bought a house, and want to start a garden in the back yard. It's all grass right now, we're going to be starting from scratch. We want to take up some sections of the grass and start a garden. I'm not sure what the right way to go about this is. I've grown herbs and veggies before in pots, and maintained a small flower garden, but I've never done a full garden before. We're hoping to grow a lot of herbs, a few flowers, and hopefully lots of veggies...
