+Home Assistant will be able to automatically discover and configure any Google Chromecasts, Netgear
+routers, Belkin WeMo switches, Philips Hue bridges and Sonos speakers in your network if you have
+[the discovery component]({{site_root}}/components/discovery.html) enabled (which is by default).
+
+See the [components overview page](/components/) to find installation instructions for your devices
+and services.
+
+To get the most out of automation, it is useful to setup the following things:
+
+ * [Presence Detection](/components/#presence)
+ * [Notification service](/components/#notify-service)
+
+If you can't find support for your favorite device or service,
+[consider adding support](/developers/add_new_platform.html)

+### {% linkable_title Grouping devices %}
+
+Once you get a bunch of devices set up, it is time to organize them. This can be done using groups.
+Each group exists of a name and a list of entity IDs. Entity IDs can be retrieved from the web interface
+by using the Set State page in the Developer Tools (icon in the middle).
+
+
+```yaml
+# Example configuration.yaml entry
+group:
+  living_room: light.table_lamp, switch.ac
+  bedroom:
+    - light.bedroom
+    - media_player.nexus_player
+```
+
+### {% linkable_title Customizing devices and services %}
+
+By default, all of your devices will be visible and have a default icon determined by their domain.
+You may find it desireable to customize the look and feel of your front page by altering some
+of these parameters. This can be done by adding the following config to the `homeassistant:` section.
+
+```yaml
+# Example configuration.yaml entry
+homeassistant:
+
+    # Add this to your existing configuration
+    customize:
+        some.entity_id:
+            hidden: true
+            entity_picture: http://placehold.it/200x200
+            friendly_name: My better name
+```
