2. Visit https://developers.facebook.com/apps
3. Click on Create New App
4. Fill-in the App Name
5. You will be redirected to the Basic settings page
6. Now copy the App ID value. This is your client ID
7. Then copy the App Secret value. This is your client secret

Note: The values need to be stored in the spring.properties file (see Part 5).
