I don't know how to add the Widgetized Home (Magazine) Can you help me step by step please?

Basically you need to set the front page to display latest posts, then drag the widgets into the 3 sidebars (HomePage Big, Medium, Small), preferably the ones whose name starts with the HP prefix, and/or carousels.

Activate sliders and the vertical carousel in the “Sliders” Tab, and feature some posts in them as described in the documentation.
