+# 🤗 Optimum OpenVINO Notebooks
+
+This directory contains notebooks for the OpenVINO integration in 🤗 Optimum. To
+install the requirements for running all notebooks, do `pip install -r
+requirements.txt`. If you do not want to install the requirements to run all the
+notebooks, you can also install the requirements for a specific notebook. They
+are listed at the top of each notebook file.
+
+The notebooks have been tested with Python 3.8 and 3.10 on Ubuntu Linux.
