Adding Web Part to a SharePoint site
Go to SharePoint site where you want to add the web part and open “Site Actions - Edit page”. You will switch to edit mode.
Click “Add a Web Part”.
Select Virto Pivot View at the bottom of the list and click “Add”.
Once you have clicked “Add” button, use “Exit edit mode” button.
The added web part will be displayed on page. To adjust it, go to web part settings.
In more recent versions of SharePoint choose “Edit” on a page, then select “Insert” button on the ribbon and add “Virto Pivot View” Web Part from the list.
