+# Multi Processor Trace Example
+
+In this example, the application in `main.cc` initializes and registers a tracer
+provider from the [OpenTelemetry
+SDK](https://github.com/open-telemetry/opentelemetry-cpp). The `TracerProvider` is connected
+to two `processor-exporter` pipelines - for exporting simultaneously to `StdoutSpanExporter`
+and `InMemorySpanExporter`. 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 telemetry is directed to stdout through the StdoutSpanExporter, and saved as a
+variable (vector of spans) through `InMemorySpanExporter`.
+
+See [CONTRIBUTING.md](../../CONTRIBUTING.md) for instructions on building and
+running the example.
