How to bring a Mustang back to life

Hi,

I have had a Mustang sitting in my garage for quite a few years. I am finally giving my self the time to get it running and hope to have on the road by Spring. Let's just say that my life got in the way of keeping this car on the road. Although, I never considered selling it. My question to you techies is "What is the proper procedure to get a dormant car running again?". Rather than telling you what I was going to do, does anyone have their tried and true process? The Mustang was running when I stopped driving it. Any words of wisdom are appreciated. You can even lecture me about not keeping it alive over these years. I realize that wasn't the best thing I could have done to the car. Thanks.
