Atlassian utilizes Scroll add-ons to enhance its documentation process, employing Scroll Viewport for theming and Scroll Versions for version management, enabling tech writers to synchronize their work with development teams. This system allows for the creation of multiple versions and effective content management while providing a responsive experience for users. Ultimately, Atlassian's approach streamlines documentation by keeping all information centralized in Confluence, supporting both cloud and server documentation needs.
