+
+### About tracking issues
+
+Tracking issues are used to record the overall progress of implementation.
+They are also used as hubs connecting to other relevant issues, e.g., bugs or open design questions.
+A tracking issue is however *not* meant for technical discussion, questions, or bug reports.
+Instead, open a dedicated issue for the specific matter, link to this tracking issue and ping the MCP author.
+Alternatively, post in the Zulip stream linked from the MCP.
+
+Discussion comments will get marked as off-topic or deleted.
+Repeated discussions on the tracking issue may lead to the tracking issue getting locked.
+
+### Steps
+
+- [ ] Implement the MCP
+- [ ] Adjust documentation
+
+### Unresolved questions
