+## Proxying OGC services through gemma
+
+- Add services you want to publish via gemma (e.g. for same-origin policy
+  compliance reasons) in the database. For example:
+  ```
+  INSERT INTO sys_admin.external_services (local_name, remote_url, is_wfs)
+    VALUES ('d4d', 'https://service.d4d-portal.info/wamos/wfs', true);
+  ```
+  In case your gemma is already running (see previous section), restart it.
+  The services will be available at `/api/external/${local_name}`, thus in
+  the example given above: `/api/external/d4d`.
