+            LangFlow is a UI for creating workflows with LLMs. This One-Click App requires a superuser 
+            username and password for login, ensuring security. The secret key is auto-generated for securing 
+            sensitive data. Ensure you have PostgreSQL installed and configured. If not, you can install PostgreSQL 
+            using the CapRover One-Click App Store and configure it by setting the database name to `langflow` and 
+            using your own username and password.
+
+            Remember to update the PostgreSQL connection string to match your setup.
+        end: >
+            LangFlow is deployed and available at `$$cap_appname`. It might take a few
+            minutes for the service to initialize.
