Well, it would have been helpful to provide a simple example of a working pwa.

The example at

https://codelabs.developers.google.com/codelabs/your-first-p...

was way too complicated as a first example, if all I wanted to know was how to make my app installable and is also broken as it uses some outdated tools. (don't remember the details)

Also, it could have been mentioned somewhere, that when you serve from localhost, you do not need SSL to install it. Knowing that, would have saved me the trouble of messing with apaches config and certificates.

So that was very frustrating as a start.

Much more helpful was a very simple hello world pwa which was barely installable. But it worked. And from there it was easy.
