Camera path around a Mobius type ring

I have made an inscribed 90° twisted Mobius ring
I have been trying to create a camera path that follows the writing so it can be read. I extracted an edge of the ring that I can use with “Constraints” but it is offset from the centre of the writing. I would like to move the camera over the writing and for it to tilt according to the slope of the Ring’s surface. (Like a plane banking.)
Any suggestions or is using “Constraints” the wrong way to go about it?
