 * Create or update file contents

 * Creates a new file or replaces an existing file in a repository. You must authenticate using an access token with the `workflow` scope to use this endpoint.

**Note:** If you use this endpoint and the "[Delete a file](https://docs.github.com/rest/reference/repos/#delete-file)" endpoint in parallel, the concurrent requests will conflict and you will receive errors. You must use these endpoints serially instead.
