-## Requirements
+## Adding to your dashboard
 
-Your system needs to have the `de_DE.utf8` locale installed in order to parse the dates from the scraped web response.
+You can add an overview of the current infection numbers to your dashboard using the [multiple-entity-row](https://github.com/benct/lovelace-multiple-entity-row) card:
+
+```yaml
+type: entities
+entities:
+  - type: custom:multiple-entity-row
+    entity: sensor.coronavirus_augsburg
+    entities:
+      - attribute: total_cases
+        name: Cases
+      - attribute: num_dead
+        name: Deaths
+      - attribute: num_recovered
+        name: Recovered
+      - attribute: num_infected
+        name: Infected
