The first time you use Home layout do not be afraid if only you see is a gray space, that is normal.
It is because you have to configure your personalized landing page first.
<add key="WelcomeMessageH1" value="YOUR MESSAGE HERE." />
<add key="WelcomeMessageH3" value="Your message here." />
If you have any questions or suggestions, you can email to firstname.lastname@example.org. These will be of great value.
