+Install Shutoh by running:
 ```
 pip install git+https://github.com/awkrail/shutoh.git
 ```
 To detect scenes with `ContentDetector()`, run the following code:
 ```python
 from libshutoh import detect, ContentDetector
-detector = ContentDetector.initialize_detector()
+detector = ContentDetector.initialize_detector(threshold=27, min_scene_len=15)
+scenes = detect('video/input.mp4', detector)

+        scene[0].get_timecode(), scene[0].get_frames(),
+        scene[1].get_timecode(), scene[1].get_frames(),))
+```
+Using `scenedetect.split_video_ffmpeg`, we can also split the video into each scene:
+```python
+from libshutoh import detect, ContentDetector
+from scenedetect import split_video_ffmpeg
+detector = ContentDetector.initialize_detector(threshold=27, min_scene_len=15)
 scenes = detect('video/input.mp4', detector)
+split_video_ffmpeg('vide/input.mp4', scenes, show_progress=True)
 ```
-See [Python API documentation](docs/python_documentation.md) for details.
+If you want to use other detectors, replace the detector with the new one:
+```python
+from libshutoh import AdaptiveDetector
+detector = AdaptiveDetector.initialize_detector()
