iSlides is an add.in for PowerPoint based on VSTO (Visual Studio Tools for Office) technology.
Through an installation wizard that you can find in our downloads page, you can enable iSlides so it been added to your PowerPoint as add-in. You must follow the steps indicated in the installation wizard.
Once the installation process is complete, when you come back to open PowerPoint, you could find a new tab called iSlides.

From that tab, click in the icon related with the presentation that you wanted to create.
A menu will open from which you can select one or more diagrams, each of which will then appear as a separate slide in your presentation.
And ready!
From now on, you will be able to modify your presentations both in edit mode and in slide show mode.
