+#### Custom Video Demo
+
+To run the demo with your custom video or frame directory, use the following examples:
+
+**Note:** The `.txt` file contains a single line with the bounding box of the first frame in `xywh` format.
+
+Replace `<path_to_first_frame_bbox.txt>` with the path to your `.txt` file and `<your_video.mp4>` with your video file path, or replace it with the directory path if you want to process frames from a folder.
+
+### Input is Video File
+If your input is a video file, run the following command:
+
+```
+python scripts/demo.py --video_path <your_video.mp4> --txt_path <path_to_first_frame_bbox.txt>
+```
+
+### Input is Frame Folder
+If your input is a directory of frames, run the following command:
+```
+python scripts/demo.py --video_path <your_frame_directory>/ --txt_path <path_to_first_frame_bbox.txt>
+```
