-places to ask questions, for example Stack Overflow.

-If you want to ask a question anyway, please make sure that:
-
-- it's a question about websockets and not about :mod:`asyncio`;
-- it isn't answered in the documentation;

+Getting support
+===============
+
+.. admonition:: There are no free support channels.

+
+    websockets is an open-source project. It's primarily maintained by one
+    person as a hobby.
+
+    For this reason, the focus is on flawless code and self-service
+    documentation, not support.
+
+Enterprise
+----------
+
+websockets is maintained with high standards, making it suitable for enterprise
+use cases. Additional guarantees are available via :doc:`Tidelift <tidelift>`.
+If you're using it in a professional setting, consider subscribing.
