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?

Revisa el contexto de licenciamiento CC BY 4.0 del repositorio y la licencia MIT propuesta para el proyecto, y aborda después las preguntas sobre la atribución planteadas aquí. Se considera terminado cuando se haya proporcionado una orientación clara sobre dónde debe aparecer la atribución, si la documentación necesita un repositorio separado y cómo gestionar las cabeceras de archivo mostradas.
