+# Examples
+
+These are example uses of the oidc package. Each requires a Google account and the
+client ID and secret of a registered OAuth2 application. The client ID and secret
+should be set as the following environment variables:
+
+```
+GOOGLE_OAUTH2_CLIENT_ID
+GOOGLE_OAUTH2_CLIENT_SECRET
+```
+
+See Google's documentation on how to set up an OAuth2 app:
+https://developers.google.com/identity/protocols/OpenIDConnect?hl=en
+
+Note that one of the redirect URL's must be "http://127.0.0.1:5556/auth/google/callback"
