 <Admonition type="note" title="Database CLI compatibility">
-  While the terminal interface looks similar to database CLIs like `psql`, it is
-  a custom implementation provided by Teleport. As a result, it may give
-  different behaviors and a distinct feature set compared to commonly used
-  database CLI tools.
+  While the terminal interface provided in the Teleport Web UI is designed to
+  resemble popular database CLIs such as `psql`, it is a custom implementation
+  with some differences and limitations:
+  - **Feature Set:** Not all features available in `psql` are implemented.
+    For instance, scripting capabilities, query cancelation, or informational
+    commands like `\d` or `\dt` are currently unsupported.
+  - **Error Handling:** Error messages and diagnostics might differ from what
+    users are accustomed to in `psql`.
+
+  These distinctions are designed to maintain a lightweight and secure interface
+  directly in your browser. For more complex operations, you may prefer
+  accessing your database from your terminal using `tsh` and your preferred
+  tool.
+
+  Future updates may expand functionality or address feedback based on user
+  needs and supported databases.
