+### Using Docker Compose secrets
+
+You can use Docker Compose secrets to not expose sensitive information in your compose file, using a `.env` file.
+
+```dotenv
+# file secrets.env
+OG_GITLAB_CLIENT_KEY=your_gitlab_client_key
+OG_GITLAB_SECRET=your_gitlab_secret_key
+```
+
+And then use it in your compose file :
+
+```yml
+services:
+  opengist:
+    # ...
+    secrets:
+      - opengist_secrets
+
+secrets:
+  opengist_secrets:
