-              - Now we know where there's a marker
+              - Now we know _where_ there's a marker
                 - Which way is it facing?
               - We know where the corners are
-                - We can get the angle from that
-                - Much like when we removed distortion
-                - If we know the size of the marker, we can calculate its distance
-              - Some calibration per camera model is required
-                - Done once upfront
-              - Out the end, we get rotation and translations from the camera
+              - Find out translation and rotation
                 - _complicated maths_
                   - `solvePnP` in OpenCV (entertaining name)
                     - "Perspective 'n' Point"
+                - If we know the size of the marker, we can calculate its distance
+              - Some calibration per camera model is required
+                - Done once up-front
               - With simpler maths, can be turned into angles, distances etc
