Can i use 1 Tag instead of 3?

If you want to use 1 Tag you'll need to modify the code. You can start by looking at the do_predock() function, and change the line centre_tf = self.get_centre_of_side_markers() to something that uses only 1 marker.

Preempting the question of why 3 markers are used instead of 1, I am not the author of the code, but I have hypothesised some reasons why the 3 Tags are used here.

Yes the above comments are right.
When looking at the state machine diagram on the readme, the sides markers are used during predock, and steerdock states. You can try to edit the way both do_single_side_marker_rotate() and get_centre_of_side_markers() are currently implemented. PR is always welcomed!
