How to integrate Netlify CMS for clients' sites

I am working on two sites for a client of which I intend to use Netlify CMS, I am lost on how I can setup Netlify CMS for them since I am not the one going to be using the site. I want both the GitHub repository and the Netlify hosting to be on their own account, as well as the CMS ready for them to use when they navigate to /admin

Hi Edmund,

You’ll need to create the repo using the github account you want it linked to in production, and generate the git-gateway token using that user’s github account. Can you provide more information on where you are being blocked? Any errors you’re seeing? details help. Thanks!
