RN wanting to transition into Clinical Documentation Specialist

I am looking for some Clinical Documentation Specialist out there! I have been a RN for 7 years and I am looking to transition into a CDS profession. I really don't know where to start. I do have some coding and insurance experience when I was a medical secretary before I became a RN. I don't know if that will be good enough. Could anyone point me into some direction? Thank you in advance
