A social provider implementation should be able to provide help to how to configure it.
This should be returned as a html snippet.
In the admin console for social providers that provide these instructions there should a help sign next to it that opens a modal panel with the instructions. See attached screenshot.
For example for Google it would be something like:
Open <a href="https: target="_blank">https://cloud.google.com/console/project</a>.
Click <i>Create Project</i>.
<p>Use any project name and id that you'd want and click <i>Create</i>. Wait for the project to be created.</p>
<p>Click <i>APIs & auth</i>, under <i>APIs</i> make sure <i>Google+ API</i> is <i>ON</i>.
<p>Click <i>Credentials</i> and click on <i>Create New Client ID</i>. Select <i>Web application</i> as <i>Application
URI</i>. Click <i>Create Client ID</i></p>.
