It discusses that Smarty was created by Andrei Zmievski and separates display logic from controller logic for improved security and ease of use. Key features covered include literal tags, modifiers, and capture/cycle functions that allow for powerful templating capabilities. Examples demonstrate how to output variables, format dates, and alternate content display. Resources listed provide more documentation on Smarty syntax and usage.
