+#### Web App Manifest
+
+[Web App Manifest](https://developers.google.com/web/fundamentals/web-app-manifest/) is a simple json file with basic site info like name, description, icons, etc. This file tells the browser about your web application and how it should behave when "installed" (as PWA) on the users mobile device or desktop.
+
+To activate Web App Manifest you need to define `MANIFEST` custom output format & specify `[Params.Manifest]` parameters in your site config file.
+
+First of all, you should define `MANIFEST` custom output format [`config.toml`]:
+
+```toml
+[outputFormats]
+  [outputFormats.MANIFEST]
+    mediaType = "application/json"
+    baseName = "manifest"
+    isPlainText = true
+    notAlternative = true
+```
+
+Then, include `MANIFEST` output format for `home` Kind attribute [`config.toml`]:
+
+```toml
+[outputs]
+  home = ["HTML", "RSS", "MANIFEST"]
+```
+
+After that, you can specify `[Params.Manifest]` parameters.
+
+*To verify that your manifest file is configured properly and works well, run Hugo server and open Chrome DevTools (Press F12 in Chrome) → Application → Manifest*
