+DESCRIPTION = """
+The steps are the following:
+
+- Paste a read-access token from hf.co/settings/tokens. Read access is enough given that we will open a PR against the source repo.
+- Input a model id from the Hub
+- Input the filename from the root dir of the repo that you would like to convert, e.g. 'xl-pruned.safetensors'
+- Click "Submit"
+- That's it! You'll get feedback if it works or not, and if it worked, you'll get the URL of the opened PR 🔥
+
+⚠️ If you encounter weird error messages, please have a look into the Logs and feel free to open a PR to correct the error messages.
