Just insert a new mockup, name it and save. The mockup will show up as an image on the page. Every version of the mockup is saved as a page attachment, both as an image and as clean, human-readable XML data.
Mockups works with Confluence 3.5 to the latest Confluence version. It also comes pre-installed on Atlassian OnDemand.
Give it a try on your own Confluence installation, for 30 days, free of charge.
For support, please see our Documentation for Confluence Plugin, our Mockups for Confluence forum on Get Satisfaction, or send us email. Confluence Administrators, the Mockups for Confluence Admin Guide is for you.
We follow a very similar pricing model as Confluence, for an extra-easy purchasing process. In short, Balsamiq Mockups costs more or less half of what Confluence does.
