 ### Inference/Demo
-```Shell
-# Coming soon
+See `tools/detect.py` for detailed information.
+```
+python tools/detect.py --help
+
+usage: detect.py [-h] [--img IMG] [--show] [--savedir SAVEDIR]
+                 [--load_from LOAD_FROM]
+                 config

+positional arguments:
+  config                The path of config file
