Web App Manifest installability

One of the most important requirements of a PWA (Progressive Web App) is installability: by installing a PWA, it will be possible to add it to the home screen of the device and thus make it easier for users to interact with it more often.

In order to make the PWA installable, a Web App Manifest is required, as it has key pieces of information needed.

How can I check that my PWA is installable?

Make sure the page's manifest has these properties:
