The map of France shown below consists of 22 regions. To show the functionality within the atlas function first choose a print composer or create a new one. I will assume that you are familiar with how to use the print composer.
Next we can put some relevant information within the body of each map. Create a second label and place it in the center of the map within the Print Composer. Use the Insert an expression option to create the following text: 'The region code for ' || "Name_Regio" || ' is ' || "Code_Regio" || '.' || '\n' || 'The population of ' || "Name_Regio" || '\n' || ' is ' || format_number( "Population",0 ). Alternatively, you can enter the text directly in the Label - Main properties section after removing the default QGIS text. If you enter the text directly you will have to manually insert the [% ..%] at the beginning and end of the text. An example of the output from the atlas is shown below.
