-# Distributed version of the Spring PetClinic Sample Application built with Spring Cloud 
+# Spring PetClinic 
 
 [![Build Status](https://travis-ci.org/spring-petclinic/spring-petclinic-microservices.svg?branch=master)](https://travis-ci.org/spring-petclinic/spring-petclinic-microservices/) [![License](https://img.shields.io/badge/License-Apache%202.0-blue.svg)](https://opensource.org/licenses/Apache-2.0)
 
+Distributed version of the Sample Application built with Spring Cloud. Instrumented with the Splunk distribution of the OpenTelemetry Java Instrumentation and accompanied by OpenTelemetry Collector.
+
+
 This microservices branch was initially derived from [AngularJS version](https://github.com/spring-petclinic/spring-petclinic-angular1) to demonstrate how to split sample Spring application into [microservices](http://www.martinfowler.com/articles/microservices.html).
 To achieve that goal we use Spring Cloud Gateway, Spring Cloud Circuit Breaker, Spring Cloud Config, Spring Cloud Sleuth, Resilience4j, Micrometer 
 and the Eureka Service Discovery from the [Spring Cloud Netflix](https://github.com/spring-cloud/spring-cloud-netflix) technology stack.
 
-## Starting services locally without Docker
+## Starting the application with instrumentation
+
+In order to start the application as configured for Splunk OpenTelemetry distribution, simply run `start.sh`. The script will:
+- download the agent
+- build Docker images
+- run all microservices using Docker compose
 
-Every microservice is a Spring Boot application and can be started locally using IDE or `../mvnw spring-boot:run` command. Please note that supporting services (Config and Discovery Server) must be started before any other application (Customers, Vets, Visits and API).
-Startup of Tracing server, Admin server, Grafana and Prometheus is optional.
 If everything goes well, you can access the following services at given location:
 * Discovery Server - http://localhost:8761
 * Config Server - http://localhost:8888
 * AngularJS frontend (API Gateway) - http://localhost:8080
 * Customers, Vets and Visits Services - random port, check Eureka Dashboard 
+* Otel Collector - http://localhost:55680
 * Tracing Server (Zipkin) - http://localhost:9411/zipkin/ (we use [openzipkin](https://github.com/openzipkin/zipkin/tree/master/zipkin-server))
 * Admin Server (Spring Boot Admin) - http://localhost:9090
 * Grafana Dashboards - http://localhost:3000
 * Prometheus - http://localhost:9091
 
-You can tell Config Server to use your local Git repository by using `native` Spring profile and setting
-`GIT_REPO` environment variable, for example:
-`-Dspring.profiles.active=native -DGIT_REPO=/projects/spring-petclinic-microservices-config`
+## Downloading OpenTelemetry Java Agent
+
+Download the [latest release](https://github.com/signalfx/splunk-otel-java/releases/latest/download/splunk-otel-javaagent-all.jar)
+   of the Splunk Distribution of OpenTelemetry Java Instrumentation. For example use: 
+   ```bash
+   $ # download the newest version of the agent
+   $ sudo curl -vsSL -o /opt/splunk-otel-javaagent-all.jar 'https://github.com/signalfx/splunk-otel-java/releases/latest/download/splunk-otel-javaagent-all.jar'
+   ```
 
 ## Starting services locally with docker-compose
 In order to start entire infrastructure using Docker, you have to build images by executing `./mvnw clean install -P buildDocker`

 ## Database configuration
 
 In its default configuration, Petclinic uses an in-memory database (HSQLDB) which gets populated at startup with data.
-A similar setup is provided for MySql in case a persistent database configuration is needed.
-Dependency for Connector/J, the MySQL JDBC driver is already included in the `pom.xml` files.
-
-### Start a MySql database
-
-You may start a MySql database with docker:
-
-```
-docker run -e MYSQL_ROOT_PASSWORD=petclinic -e MYSQL_DATABASE=petclinic -p 3306:3306 mysql:5.7.8
-```
-or download and install the MySQL database (e.g., MySQL Community Server 5.7 GA), which can be found here: https://dev.mysql.com/downloads/
-
-### Use the Spring 'mysql' profile
-
-To use a MySQL database, you have to start 3 microservices (`visits-service`, `customers-service` and `vets-services`)
-with the `mysql` Spring profile. Add the `--spring.profiles.active=mysql` as programm argument.
-
-By default, at startup, database schema will be created and data will be populated.
-You may also manually create the PetClinic database and data by executing the `"db/mysql/{schema,data}.sql"` scripts of each 3 microservices. 
-In the `application.yml` of the [Configuration repository], set the `initialization-mode` to `never`.
-
-If you are running the microservices with Docker, you have to add the `mysql` profile into the (Dockerfile)[docker/Dockerfile]:
-```
-ENV SPRING_PROFILES_ACTIVE docker,mysql
-```
-In the `mysql section` of the `application.yml` from the [Configuration repository], you have to change 
-the host and port of your MySQL JDBC connection string.
