 ### Exporting Traces
 
-The following section assumes you are new to OpenTelemetry or do not currently use a vendor that supports distributed tracing using OTLP. Please refer to your vendor's product documentation if you would like to export your traces to a vendor for analysis and vizualization.

 Next, you'll have to let the SDK know where the collector endpoint is to receive traces.
 Set the [`OTEL_EXPORTER_OTLP_ENDPOINT`][sdk-env] environment variable to `http://0.0.0.0:4318`:
 
-```bash

 ### Achievement Unlocked: Tracing Enabled
 
-Adding tracing to a single service is a great first step and although auto-instrumenation provides quite a bit of insight on its own, OpenTelemetry provides a few more features that will allow you gain even deeper insights!

-[Context Propagation][context-propagation] is perhaps one of the most powerful concepts in OpenTelemetry because it will upgrade your single service trace into a _distributed trace_, which makes it possible for OpenTelemetry vendors to visualize a request from end-to-end accross process and network boundaries.

 [Span Events][events] allow you to add a human-readable message on a span that represents "something happening" during its lifetime.
