 Windows Event Tracing infrastructure is available to any vendor or application
 being deployed on Windows.
 
+## Tracer lifetime and reuse
+
+For ETW, the tracer name maps to the ETW provider name/GUID. Applications
+should create one tracer per provider name and reuse it for the process or
+component lifetime. `TracerProvider::GetTracer()` caches tracers internally,
+so avoid calling `GetTracer()->StartSpan()` in hot paths. Instead, obtain the
+tracer once during setup and reuse it for span creation.
+
+Encoding (ETW/TLD, MSGPACK, XML) is configured via `TelemetryProviderOptions`
+passed to the `TracerProvider` constructor:
+
+```cpp
+TelemetryProviderOptions opts;
+opts["encoding"] = std::string("MsgPack");
+etw::TracerProvider tp(opts);
+auto tracer = tp.GetTracer("MyProvider");
+```
+
 It is recommended to consume this exporter via
 [vcpkg](https://vcpkg.io/en/package/opentelemetry-cpp).
