 You can change these defaults either through the commandline.
 For example, to change the dataset and the image detector, you could do::
 
-    python -m tracklab.main dataset=posetrack18 detect_multiple=openpifpaf
+    uv run tracklab dataset=sportsmot bbox_detector=yolox
 
-If you want to change a single value inside a category, for example the bbox extension factor::
+If you want to change a single value inside a category, for example the number of frames per video::
 
-    python -m tracklab.main detect_multiple=openpifpaf "detect_multiple.cfg.bbox.extension_factor=[0.05,0.05,0.05]"
+    uv run tracklab dataset.nframes=10
 
-This will both change the detector to ``openpifpaf`` and change a parameter inside the openpifpaf configuration.
 
 You can find out which values you can change by looking at the configuration directory or running::
 
-    python -m tracklab.main --help
+    uv run tracklab --help
 
 Thanks to Hydra, we can also run a grid-search (or other kind of hyper-parameter searches). The default grid-search
 is activated with the ``-m`` flag, and by passing a comma-separated list of values, either at the category-level
 or at the key-level::
 
-    python -m tracklab.main -m dataset=posetrack18,posetrack21 detect_multiple=openpifpaf,yolox track.cfg.max_dist=0.2,0.5,0.7
+    uv run tracklab -m dataset=sportsmot,dancetrack track.cfg.max_dist=0.2,0.5,0.7
 
-This command will run tracking multiple times, to test two datasets, two image-level detectors with three different
-tracking hyper-parameters (combining to 12 runs).
