+### Jaeger
+
+* The Jaeger project provides an all-in-one Docker container with a UI, database, and consumer. Run the following command to start Jaeger:
+
+```sh
+$ docker run -p 16686:16686 -p 6831:6831/udp jaegertracing/all-in-one
+```
+
+* This command starts Jaeger locally on port 16686 and exposes the Jaeger thrift agent on port 6831. You can visit Jaeger at http://localhost:16686.
+
+* Install the OpenTelemetry Jaeger Exporter
+
+```sh
+$ pip install opentelemetry-exporter-jaeger
+```
+
+* Update `APPLICATIONINSIGHTS_CONNECTION_STRING` environment variable
+
+* Run the sample
+
+```sh
+$ # from this directory
+$ python sample_jaeger.py
+```
+
+* You should be able to see your traces in the Jaeger backend as well as Azure Monitor application insights backend.
+
+### Collector
+
+* Start the Collector locally to see how the Collector works in practice.
+
+* From the same folder as collector/otel-collector-config.yaml and collector/docker-compose.yml, start the Docker container.
+
+```sh
+$ docker-compose up
+```
+
+* Install the OpenTelemetry OTLP Exporter
+
+```sh
+$ pip install opentelemetry-exporter-otlp
+```
+
+* Update `APPLICATIONINSIGHTS_CONNECTION_STRING` environment variable
+
+* Run the sample
+
+```sh
+# from collector directory
+$ python sample_collector.py
+```
+
+* You should be able to see your traces in the Zipkin backend as well as Azure Monitor application insights backend.

 ### Azure Service Bus Send
 
 The following sample assumes that you have setup an Azure Service Bus [namespace](https://docs.microsoft.com/azure/service-bus-messaging/service-bus-quickstart-portal).
