-## Ecosystem
-
-### Related Crates
-
-In addition to `opentelemetry`, the [`open-telemetry/opentelemetry-rust`]
-repository contains several additional crates designed to be used with the
-`opentelemetry` ecosystem. This includes a collection of trace `SpanExporter`
-and metrics pull and push controller implementations, as well as utility and
-adapter crates to assist in propagating state and instrumenting applications.
-
-In particular, the following crates are likely to be of interest:
-
-* [`opentelemetry-aws`] provides unofficial propagators for AWS X-ray.
-* [`opentelemetry-datadog`] provides additional exporters to [`Datadog`].
-* [`opentelemetry-dynatrace`] provides additional exporters to Dynatrace.
-* [`opentelemetry-contrib`] provides additional exporters and propagators that
-  are experimental.
-* [`opentelemetry-http`] provides an interface for injecting and extracting
-  trace information from [`http`] headers.
-* [`opentelemetry-jaeger`] provides context propagation using [jaeger propagation format](https://www.jaegertracing.io/docs/1.18/client-libraries/#propagation-format).
-* [`opentelemetry-otlp`] exporter for sending trace and metric data in the OTLP
-  format to the OpenTelemetry collector.
+## Overview of crates
+
+The following crates are maintained in this repo:
+
+* [`opentelemetry`] This is the OpenTelemetry API crate, and is the crate
+  required to instrument libraries and applications. It contains Context API,
+  Baggage API, Propagators API, Logging Bridge API, Metrics API, and Tracing
+  API.
+* [`opentelemetry-sdk`] This is the OpenTelemetry SDK crate, and contains the
+  official OpenTelemetry SDK implementation. It contains Logging SDK, Metrics
+  SDK, and Tracing SDK. It also contains propagator implementations.
+* [`opentelemetry-otlp`] - exporter to send telemetry (logs, metrics and traces)
+  in the [OTLP
+  format](https://github.com/open-telemetry/opentelemetry-specification/tree/main/specification/protocol)
+  to an endpoint accepting OTLP. This could be the [OTel
+  Collector](https://github.com/open-telemetry/opentelemetry-collector),
+  telemetry backends like [Jaeger](https://www.jaegertracing.io/),
+  [Prometheus](https://prometheus.io/docs/prometheus/latest/feature_flags/#otlp-receiver)
+  or [vendor specific endpoints](https://opentelemetry.io/ecosystem/vendors/).
+* [`opentelemetry-stdout`] exporter for sending logs, metrics and traces to
+  stdout, for learning/debugging purposes.  
+* [`opentelemetry-http`] This crate contains utility functions to help with
+  exporting telemetry, propagation, over [`http`].
+* [`opentelemetry-appender-log`] This crate provides logging appender to route
+  logs emitted using the [log](https://docs.rs/log/latest/log/) crate to
+  opentelemetry.
+* [`opentelemetry-appender-tracing`] This crate provides logging appender to
+  route logs emitted using the [tracing](https://crates.io/crates/tracing) crate
+  to opentelemetry.  
+* [`opentelemetry-jaeger-propagator`] provides context propagation using [jaeger
+  propagation
+  format](https://www.jaegertracing.io/docs/1.18/client-libraries/#propagation-format).
 * [`opentelemetry-prometheus`] provides a pipeline and exporter for sending
-  metrics information to [`Prometheus`].
+  metrics to [`Prometheus`].
 * [`opentelemetry-semantic-conventions`] provides standard names and semantic
   otel conventions.
-* [`opentelemetry-stackdriver`] provides an exporter for Google's [Cloud Trace]
-  (which used to be called StackDriver).
-* [`opentelemetry-zipkin`] provides a pipeline and exporter for sending trace
-  information to [`Zipkin`].
-
-Additionally, there are also several third-party crates which are not
-maintained by the `opentelemetry` project. These include:
-
-* [`tracing-opentelemetry`] provides integration for applications instrumented
-  using the [`tracing`] API and ecosystem.
-* [`actix-web-opentelemetry`] provides integration for the [`actix-web`] web
-  server and ecosystem.
-* [`opentelemetry-application-insights`] provides an unofficial [Azure
-  Application Insights] exporter.
-* [`opentelemetry-tide`] provides integration for the [`Tide`] web server and
-  ecosystem.
-* [`trillium-opentelemetry`] provides metrics instrumentation for [`trillium`] http servers following [semantic-conventions](https://github.com/open-telemetry/semantic-conventions/blob/main/docs/http/http-metrics.md).
