+# Jaeger Exporter Example
+
+This is an example of how to use the Jaeger exporter.
+
+The application in `main.cc` initializes an `JaegerExporter` instance and uses it
+to register a tracer provider from the [OpenTelemetry
+SDK](https://github.com/open-telemetry/opentelemetry-cpp). The application then
+calls a `foo_library` which has been instrumented using the [OpenTelemetry
+API](https://github.com/open-telemetry/opentelemetry-cpp/tree/main/api).
+
+Resulting spans are exported to the Jaeger agent using the Jaeger exporter.
+
+Note that the Jaeger exporter connects to the agent at `localhost:6831` by
+default.
+
+Once you have the Collector running, see
+[CONTRIBUTING.md](../../CONTRIBUTING.md) for instructions on building and
+running the example.
