+## 3. [Create a pull request](https://huggingface.co/docs/hub/repositories-pull-requests-discussions#pull-requests-advanced-usage)
 The pull requests on Hugging Face do not use forks and branches, but instead custom “branches” called `refs` that are stored directly on the source repo.
 
 The advantage of using custom `refs` (like `refs/pr/42` for instance) instead of branches is that they’re not fetched (by default) by people cloning the repo, but they can still be fetched on demand.

+Fetch the remote PR branch `ref/pr/<index>` to local PR branch. Then checkout to the newly created custom branch under references `pr/`, and just for unambiguity, using the PR index as the name of that reference. You can actually create a new branch locally here as usual.
