Adding a new project to a Confluence page
Adding a new Balsamiq project to a wiki page is very similar to adding an image:
Edit the page, position the cursor where you’d like your wireframe to be, then click on the Insert menu and select “Balsamiq” from the list.
This will launch the Balsamiq editor, where you can create your wireframes (or import existing ones). This will also create a new Balsamiq Project file (.bmpr file extension) attached to your wiki page containing all the resources that belong to a project (wireframes, symbols, images, icons).
If you do not see the menu item, please check with your Confluence administrator that the Balsamiq for Confluence app is installed and that you have editing permission on the current page.
