+      Dashy, a highly customizable, easy to use, privacy-respecting dashboard app.
+
+      Note that this builds a static web app as opposed to running a full node server, unlike the default docker image.
+      Writing config changes to disk through the UI, triggering a rebuild through the UI and application status checks are
+      unavailable without the node server; Everything else will work fine.
+      See the deployment docs for [building from source](https://dashy.to/docs/deployment#build-from-source), [hosting with a CDN](https://dashy.to/docs/deployment#hosting-with-cdn) and [CDN cloud deploy](https://dashy.to/docs/deployment#cdn--cloud-deploy) for more information.

+        If left empty, the default configuration shipped with the package will be used instead.
+
+        Note that the full configuration will be written to the nix store as world readable, which may include secrets such as [password hashes](https://dashy.to/docs/configuring#appconfigauthusers-optional).
+
+        To add files such as icons or backgrounds, you can reference them in line such as
+        ```nix
+        icon = "$\{./icon.png}";
+        ```
+        This will add the file to the nix store upon build, referencing it by file path as expected by Dashy.
