+The updated WIT configuration exposes the generalized wormhole parameters
+(e.g., ``n_qubits_per_side`` and ``insert_message_method``), letting you dial in new circuit sizes without
+touching the Python code.

       If the default branch or file location changes, update the URL above accordingly.
+      The example config uses ``n_qubits_per_side = 3`` with ``insert_message_method = "swap"``, producing
+      a seven-qubit circuit consistent with the original benchmark. Adjust these parameters to explore other
+      circuit sizes.
