+# Kraft REST API with Telemetry Example
+
+This example is about how to build a REST API using the Kraft web framework,
+while integrating telemetry monitoring through
+[Cowboy Telemetry](https://github.com/beam-telemetry/cowboy_telemetry).
+
+> [!TIP]
+> [Cowboy Telemetry](https://github.com/beam-telemetry/cowboy_telemetry) is a
+> prerequisite for using
+> [opentelemetry_cowboy](https://hexdocs.pm/opentelemetry_cowboy/readme.html),
+> a Telemetry handler that translates Cowboy events into OpenTelemetry spans,
+> enabling HTTP request/response instrumentation.
