+### Additional services
+
+For any additional service (without specific resources), ConfigGenerator generates the configuration in `OUTPUT_CONFIG_PATH` directory.
+
+Add the following configuration and adapt it to your service in `tenantConfig.json`:
+
+```json
+{
+    "name": "<service_name>",
+    "schema_url": "<service_schema_url>",
+    "config": {...}
+}
+```
+
+*Note*: `service_name` is expected to be camel case (i.e. `adminGui`), and the service name in the generated config will lowercase and hyphenated (i.e. `admin-gui`).
