+# DigiComp.FlowWebManifestUtils
+
+This package provides small helpers to provide a PWA webmanifest.
+
+It consists of two parts: a middleware, which will return the manifest to the browser and a view helper, which makes
+it easy to integrate your manifest to your (fluid template).
+
+All you need to do is to integrate the Manifest-VieHelper to the `head` section of your template and adjust the 
+`DigiComp.FlowWebmanifestUtils.manifest` values in Settings.yaml to match your needs.
+
+Let me provide you an example:
+```html
+<html>
+<head>
+    <DigiComp.FlowWebmanifestUtils:WebManifest />
+</head>
+</html>
+```
+
+That is the minimum you need to do, to have working manifest for your application.
+
+The start_url - Parameter in the
