+            Photoview is a simple and user-friendly photo gallery that's made for photographers and aims to provide an easy and fast way to navigate directories, with thousands of high-resolution photos.
+
+
+            You configure Photoview to look for photos and videos within a directory on your file system.
+            The scanner automatically picks up your media and start to generate thumbnail images to make browsing super fast.
+
+
+            When your media has been scanned they show up on the website, organised in the same way as on the filesystem.
+        end: >-
+            Photoview has successfully deployed.
+
+            Finish the setup at http://$$cap_appname.$$cap_root_domain.

+              To enable map related features, you need to create a mapbox token.
+
+              A token can be generated for free here https://account.mapbox.com/access-tokens/
+
+              It's a good idea to limit the scope of the token to your own domain, to prevent others from using it.
+
+              Leave empty to disable map related features.
