Installation
Scroll Sites is currently only available as part of a private beta program that you can sign up for.
If you have been invited to the beta, you can simply install Scroll Sites for Confluence Cloud from the Scroll Viewport app listing on the Atlassian Marketplace.
You will need Confluence administrator’s permission to install the app.
After installation, you will find both Scroll Viewport and Scroll Sites listed under Apps in your Confluence main navigation.
