In practice, I usually create the manifest when I create the favicons.

For details, see Using Favicons

The key is

<link rel="manifest" href="/manifest.json">

Check file favicons/manifest.json, should look something like

    "short_name": "John Vincent",
    "name": "John Vincent Portfolio",
    "icons": [
            "src": "\/favicons\/android-chrome-192x192.png",
            "sizes": "192x192",
            "type": "image\/png"
