The tutorial series describes the process of building a Progressive Web Application (PWA) with Django as the backend framework and Angular as the frontend framework. The application is built to be installable on mobile devices, functional offline, and re-engageable through push messages and notifications. The steps include setting up the project, installing necessary packages, creating a service worker, generating a manifest file, and configuring caching and security settings. The tutorial concludes with testing the PWA's functionality using Lighthouse and demonstrating its offline capabilities and ability to add custom touch icons to mobile devices' home screens.
