What are the residency requirements for an uncontested divorce?

My wife and I lived in Texas and separated there after four years of marriage. We both want a civil uncontested divorce. I moved to Detroit two months ago after we separated. She has asked me to proceed with finalizing the divorce between us. Am I able to file for an uncontested divorce here in Michigan, or does she need to be the one to do it in Texas? How long do I have to live here before I can file? I also need to know if there is a requirement that we be living separate for a certain period of time before either of us can file for the uncontested divorce.
