+This Space allows you to automatically convert 🤗 transformers PyTorch models hosted on the Hugging Face Hub to [ONNX](https://onnx.ai/). It opens a PR on the target model, and it is up to the owner of the original model
 to merge the PR to allow people to leverage the ONNX standard to share and use the model on a wide range of devices!
 
-Once converted, the model can for example be used in the [🤗 Optimum](https://huggingface.co/docs/optimum/) library following closely the transormers API.
+Once converted, the model can, for example, be used in the [🤗 Optimum](https://huggingface.co/docs/optimum/) library closely following the transformers API.
 Check out [this guide](https://huggingface.co/docs/optimum/main/en/onnxruntime/usage_guides/models) to see how!

+The steps are as following:
 - Paste a read-access token from [https://huggingface.co/settings/tokens](https://huggingface.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 (for example: [textattack/distilbert-base-cased-CoLA](https://huggingface.co/textattack/distilbert-base-cased-CoLA))
 - Click "Convert to ONNX"
-- 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!
+- That's it! You'll get feedback on if the conversion was successful or not, and if it was, you'll get the URL of the opened PR!
 
 Note: in case the model to convert is larger than 2 GB, it will be saved in a subfolder called `onnx/`. To load it from Optimum, the argument `subfolder="onnx"` should be provided.
