+## What not to use it for?
+
+Please don't use gofakes3 as a production service. The intended use case for
+gofakes3 is currently to facilitate testing. It's not meant to be used for
+safe, persistent access to production data at the moment.
+
+There's no reason we couldn't set that as a stretch goal at a later date, but
+it's a long way down the road, especially while we have so much of the API left
+to implement; breaking changes are inevitable.
+
+In the meantime, there are more battle-hardened solutions for production
+workloads out there, some of which are listed in the "Similar Notable Projects"
+section below.
