+Make Odoo an installable Progressive Web Application.
+
+Progressive Web Apps provide an installable, app-like experience on desktop and mobile that are built and delivered directly via the web.
+They're web apps that are fast and reliable. And most importantly, they're web apps that work in any browser.
+If you're building a web app today, you're already on the path towards building a Progressive Web App.

+After having installed this module, browsing your odoo on mobile you will be able to install it as a PWA.
+
+It is strongly recommended to use this module with a responsive layout, like the one provided by web_responsive.
+
+This module is intended to be used by Odoo back-end users (employees).
+
+When a Progressive Web App is installed, it looks and behaves like all of the other installed apps.
+It launches from the same place that other apps launch. It runs in an app without an address bar or other browser UI.
+And like all other installed apps, it's a top level app in the task switcher.
+
+In Chrome, a Progressive Web App can either be installed through the three-dot context menu.
+
+This module also provides a "Install PWA" link in Odoo user menu.
