-Making area's more useful
+Areas have been around for a bit already. But, not everything supports
+area's yet. And using it in, for example YAML-based automations, is not really
+an easy task to do.
 
-- You can now assign an area to entities, this is useful for entities that don't
-  have a device, or when the entities of a device are in different areas.
-- The ID of a newly created area will now be based on the name of the area instead of a random string
+Today that changes, as this release works towards making areas more useful by
+making them more accessible and more universal.
+
+The first change: individual entities can now be assigned to areas.
+
+Previously this was limited to devices only. This also works for entities
+without a device (for example, entities provided by Helpers). Devices provide
+entities, and thus it is now possible to override the area a single entity for
+a device as well. For example, your in-wall mounted switch controls a light in
+another room.

+
+Second improvement: The ID of a newly created area will now be based on the name
+of the area instead of a random string.
+
+Making it easier to use areas in service calls, as you can now use
+area identifiers that actually make sense for a human! In a YAML automation
+or script it will look like this:
+
+```yaml
+action:
+  - service: light.turn_on
+    target:
+      area_id: living_room
+```
+
+To find the area ID for the area you want to target, go to the Configuration
+Panel, and edit the area you want to target. In area edit dialog, the ID is
+shown.
