	2. Sign up for a Google account if you haven't already got an appropriate one: https://www.google.com/accounts/NewAccount
	3. Go to the Google Manage Your Domains page: https://www.google.com/accounts/ManageDomains
	4. Add a new domain.
	5. Click on the 'manage' link for the domain you added.
	6. Follow the instructions to verify the domain.
	7. Choose a Target URL. This the URL that your user is passed back to once they've finished authorizing your app at Google.
	8. Upload your X.509 certificate file.
	9. Google will provide you with an 'OAuth Consumer Key' and an 'OAuth Consumer Secret'. Save these.

		a. 'Authentication method' should be set to 'Browser Based Authentication'.

	1. Sign up for a Windows Live account if you haven't already got an appropriate one:

		c. 'Application verifier required' should be set to '0'.
