 ### Using SORT in your own project
 
 Below is the gist of how to instantiate and update SORT. See the ['__main__'](https://github.com/abewley/sort/blob/master/sort.py#L239) section of [sort.py](https://github.com/abewley/sort/blob/master/sort.py#L239) for a complete example.

-    from sort import *
-
-    #create instance of SORT
-    mot_tracker = Sort() 
-
-    # get detections
-    ...
-
-    # update SORT
-    track_bbs_ids = mot_tracker.update(detections)
 
-    # track_bbs_ids is a np array where each row contains a valid bounding box and track_id (last column)
-    ...
