This document provides an introduction and overview of the Mojolicious web framework for Perl. It notes that Mojolicious was developed by Sebastian Reidel as a flexible framework focused on the latest web technologies. Key features highlighted include flexibility through a modular design with no rigid constraints, fast prototyping capabilities, built-in web servers and real-time features, and being self-contained requiring only a single Perl distribution.
