-# Log Tracing with Spring Cloud Sleuth
-
-This project shows how to implement tracing in a network of Spring Boot applications.
-
-## Companion Blog Article
-The companion blog article to this repository can be found [here](https://reflectoring.io/tracing-with-spring-cloud-sleuth/).
-
-## Getting Started
-This application is a service facing the user (a "downstream" service), meaning that
-it accesses other upstream services to provide its functionality.
-
-1. Start the [upstream service](../sleuth-upstream-service/) with `./gradlew bootrun`
-1. Start this service with `./gradlew bootrun`
-1. Open `http://localhost:8080/customers-with-address/{id}` where IDs from 1-50 are
- will return a valid HTTP 200 response and other IDs will return an error response.
-1. Look into the log files of both services and verify that both contain the same
- trace id.

+# Tracing with Spring Cloud Sleuth, OpenTelemetry and Logz.io
+
+- run `./mvnw clean install` to build the two Spring Boot applications (`api-service` and `customer-service`)
+- run `LOGZIO_REGION= LOGZIO_TRACES_TOKEN= docker-compose up --build`
+- call `http://localhost:8080/customers/` (where ID is a number from 1 to 50)
+
+The above HTTP call goes to the `api-service`, which will call the `customer-service` for additional information. This will create a trace across both services, as should be evident in the logs with the same trace id.
+
+The `docker-compose` command also starts up an OpenTelemetry Collector, to which the Spring Boot apps send their traces. The OpenTelemetry Collector, in turn, sends the traces to Logz.io.
