Rigs From MH to Blender to UE4

Do I need to add a MH rig before I export the model from MH to Blender ? I was under the impression that I could use Rigify in Blender to add the rig. I plan to export the model to use in a game in UEngine.
I've watched tutorial videos and getting models and rigs into Unreal Engine and retargeting them from Make Human has been quite successful.
That being said.... I would like to add hair and touch up on the model in blender and wasn't sure how to go about the entire rig thing. I figured I would ask here before I tried them all multiple times.
Thanks for taking the time to help out.
