+[Jaeger](https://www.jaegertracing.io/) is an open source end to end distributed tracing system, allowing users to monitor and troubleshoot transactions in complex distributed systems.
+
+## Configuration
+
+Consult the [Jaeger documentation](https://www.jaegertracing.io/) to get started. No special changes are needed for Jaeger to work with Istio.
+
+Once Jaeger is installed, you will need to point Istio proxies to send traces to the deployment. This can be configured with `--set values.global.tracer.zipkin.address=<jaeger-collector-address>:9411` at installation time. See the [`ProxyConfig.Tracing`](/docs/reference/config/istio.mesh.v1alpha1/#Tracing) for advanced configuration such as TLS settings.
+
+## Usage
+
+For more information on using Jaeger, please refer to the [Jaeger task](/docs/tasks/observability/distributed-tracing/jaeger/).
