# What does this PR do?

This PR mentions by HF username the person who added a given model in each doc file, and updates the template so this keeps being consistently done.

A few persons are missing, tagging there below. If you are one of the persons tagged, it would be great if you could create a HF account and report your HF username here so we can properly attribute the model addition to you :-)

Thanks I just replied my name and account inline.<|||||>Hi @BigBird01, there is no huggingface account with the user name BigBird01 (I'm not talking about the GitHub account but the account on [huggingface.co](https://huggingface.co/)).<|||||>Thanks! It’s DeBERTa😊, DeBERTa (Pengcheng He) (huggingface.co)<https://huggingface.co/DeBERTa>

Thanks!

<|||||>Thank you for the mentioning!
The HF account for `bert-japanese` models is [`cl-tohoku`](https://huggingface.co/cl-tohoku).<|||||>Failure is spurious, so merging. @qiweizhen if you create (or already have) a HF account, I can add you in a followup PR.
