Where to put attribution?

I'm working on my own library and I would love to have a good and user friendly docs like ReactJS has.
As I understand I can just use some parts of this repo under CC BY 4.0 license. I'm not sure how I should mention that my documentation is based on Reacts one. Any advices are welcome. I just want to do it in a fair way. Do I have to put my documentation into separate repository than my project is located? My library is under MIT license. I'm also not sure what to do with the file headers like:

/**
 * Copyright (c) 2013-present, Facebook, Inc.
 *
 * This source code is licensed under the CC-BY-4.0 license found
 * in the LICENSE file in the root directory of this source tree.
 *
 * @emails react-core
 */

Should I leave them as they are, remove or change to my Organization?

Review the repository's CC BY 4.0 licensing context and the proposed project's MIT license, then address the attribution questions raised here. Done means providing clear guidance on where attribution belongs, whether documentation needs a separate repository, and how to handle the shown file headers.
