+## Docuseal
+
+This service displays a version string instead of a subtitle. Example configuration:
+
+```yaml
+- name: Docuseal
+  type: Docuseal
+  logo: assets/tools/sample.png
+  url: http://docuseal.example.com
+```
+
 ## Emby / Jellyfin
 
 You need to set the type to Emby, provide an api key and choose which stats to show if the subtitle is disabled.
