You are logged in to the backend of the site and want to add a block with links to the most read articles on the site. Let's add this block (or as Joomla calls it, a module).
Navigate to Extensions | Module Manager. Click New. A list of available module types is displayed:
Click on the name of the module type you want to add, Most Read Content.
The Module Manager: Module Most Read Content screen opens. This is where you manage the settings of this module. Change the details as follows:
Title: Enter a title that will appear above the list of hyperlinks to appear, such as Popular.
Position: Select the location on the page where the module is displayed. Click Type or Select a Position to display a drop-down list containing all available positions. Scroll down until you see the positions for Protostar, the current site template. Now select Right [position-7], which means that the module will appear in the right column.
