+// Package circuitbreaker implements the circuit breaker pattern.
+//
+// Circuit breakers prevent thundering herds, and improve resiliency against
+// intermittent errors. Every client-side endpoint should be wrapped in a
+// circuit breaker.

+// for guidance, Gobreaker is probably the best place to start.  It has a
+// simple and intuitive API, and is well-tested.
