+It supports both list and grouping. The number of services is not limited.

+We recommend to start familiarization with [base service](../services/base.md), on which all other services are based.
+:::

+```yaml
+services:
+  - title: Home Assistant
+    description: Home automation
+    link: https://home-assistant.home.local/
+```
+
+### Groups

+services:
+  Group 1:
+    - title: Home Assistant
