 This page will show you how to get started with OpenTelemetry in Java.
 
 You will learn how you can instrument a simple Java application automatically,
-in such a way that [traces][], [metrics][] and [logs][] are emitted to the

 ## Prerequisites
 
 Ensure that you have the following installed locally:
 
-- Java 17 JDK
+- Java JDK 17+, due to the use of Spring Boot 3; [Java 8+ otherwise][java-vers]
 - [Gradle](https://gradle.org/)
 
 ## Example Application
 
-The following example uses a basic

-not using Spring Boot, that's OK — you can use OpenTelemetry Java with other web
-frameworks as well, such as Apache Wicket and Play. For a complete list of
