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?

Revise o contexto de licenciamento CC BY 4.0 do repositório e a licença MIT proposta para o projeto e, em seguida, trate das questões de atribuição levantadas aqui. Considera-se concluído quando forem fornecidas orientações claras sobre onde a atribuição deve constar, se a documentação precisa de um repositório separado e como lidar com os cabeçalhos de arquivo mostrados.
