+By default, all of your devices will be visible and have a default icon determined by their domain. You can customize the look and feel of your front 
+page by altering some of these parameters. This can be done by adding the following configuration inside the `homeassistant:` section.
+
+Devices that you don't want to have visible can be hidden with `hidden`.  
+`entity_picture`entries, badges, `device_tracker` pictures, etc. can either be external URLs (e.g. `http://example.com/example.jpg`) or 
+of the form `/local/filename.jpg`, where `/local` represents the directory `www` in the HASS configuration directory. 
+You may have to create the `www` directory yourself as it is not made automatically.
+
+You can also use `icon` and refer to any icon from [MaterialDesignIcons.com](http://MaterialDesignIcons.com).
+
+```yaml
+# Example configuration.yaml entry
+homeassistant:
+
+  # Add this to your existing configuration
+  # Only the `entity_id` is required.  All other options are optional.
+  customize:
+    sensor.living_room_motion:
