Turning TechForSenior into a PWA

How to turn a website into a Progressive Web App (PWA)

The basic difference between creating a PWA for a website or 

just creating a Shortcut is that with a PWA you can create settings 

specific for that PWA. Something you can't do for a shortcut 

or within the browser. 

Changes in the browser affect all websites. 

Changes made to a PWA only affect that site when launched via the PWA.
