How can I install PersonalDisplay?
You first need an Android Tablet (see here). Open the Google Play Store on the tablet and search for "PersonalDisplay", then click install.
Open the application from the application list and create your account. Once created, a short walk-through will follow and PersonalDisplay will display the different screens alternatively.
To update the content, you should open the website (on the tablet or any computer) My PersonalDisplay, and login using the credentials you used on the tablet to create your account. You can now update the all the content, but also invite family or friends to manage your content.
