+For Auto IAM Authentication, make sure to run the Proxy as the same IAM
+principal as the user you want to log in as, and start the Proxy like so:
+
+``` bash
+./alloydb-auth-proxy \
+    --auto-iam-authn \

 Note: when using the query-string syntax, the instance URI and query parameters
 must be wrapped in quotes.
