How correctly specify ReactJS license in my SPA repo and contribute it?

If I understand correctly, ReactJS ships with MIT FB license.

I will plan create a repository with code based on using ReactJS as dependency in my SPA.

In my app, I want want to use another open-source license, but React MIT lisence require link to original copyright. Should I:

  • use text of original license in each file
    
  • link to it in each file of project
    
  • or can I create some like COPYRIGHTS in root of project and copy/paste the original lisence text from github (https://github.com/facebook/react/blob/27659559ebfd6b7119bfc0ff02ecb851c135020c/LICENSE) and near it create my own license
    

What is a correct way to do it ?

Thank you!
