+		This library aims to enable Metrics-Driven Development for C++ services.
+		It implements the Prometheus Data Model, a powerful abstraction on which
+		to collect and expose metrics. We offer the possibility for metrics to
+		be collected by Prometheus, but other push/pull collections can be added
+		as plugins.
