-Check out the configuration reference at https://huggingface.co/docs/hub/spaces-config-reference
+This repository relies on the submodule (back-end)
+[WebsiteYOLO](https://github.com/v-iashin/WebsiteYOLO).
+HuggingFace Spaces requires a file with requirements as `requirements.txt`
+and app code as `app.py` in the root directory.
+To rely on the submodule, I linked `gradio_requirements.txt` and `gradio_app.py`
+to `requirements.txt` and `app.py` respectively.
+
+
+## Requirements
+```yaml
+matplotlib==3.7.1
+torch==2.0.0
+```
