Setup with GitHub credentials

[hofmannsven]

I'm not sure where to create the GitHub webhook expected in the setup process and why it is necessary.

Do you want to add credentials for the GitHub API? [y/N]

The purpose of the webhook is not clear to me.
Thus I cannot reconstruct where to create the GitHub webhook. Is it a webhook for the repository or a personal access token? Furthermore, I'd like to know the required scope/permissions for the webhook.

@alpipego Feel free to drop me a short note. I'm going to document the setup process as soon as I figured it out.

If you want to contribute to the GHCP repository, you'll need to setup a GitHub Application.

I think it is only documented on how to do it for an organization: https://help.github.com/articles/installing-an-app-in-your-organization/ but it pretty much follows the same path for users (should be in https://github.com/settings/installations).

The app will be created on a organization/user profile but you can restrict its access to certain repositories. I have it set to read code and metadata on that repo. From the top of my head I don't know if reading metadata is necessary.
