+### Java Compatibility
+Powertools for AWS Lambda (Java) supports all Java version from 8 up to 21 as well as the 
+[corresponding Lambda runtimes](https://docs.aws.amazon.com/lambda/latest/dg/lambda-runtimes.html). 
+
+AspectJ does not yet support Java 21 [[1]](https://github.com/eclipse-aspectj/aspectj/issues/260), [[2]](https://github.com/eclipse-aspectj/aspectj/blob/master/docs/dist/doc/JavaVersionCompatibility.md).
+If you need to use aspects - either  Powertools features leveraging aspects or other libraries - you should use the JDK 17 compiler and target either the Java 17 or Java 21
+Lambda runtimes. 
+
 ### Installation
 
 Powertools for AWS Lambda (Java) is available in Maven Central. You can use your favourite dependency management tool to install it

     Check out [this detailed blog post](https://aws.amazon.com/blogs/opensource/simplifying-serverless-best-practices-with-aws-lambda-powertools-java/) with a practical example. To dive deeper, 
     the [Powertools for AWS Lambda (Java) workshop](https://catalog.us-east-1.prod.workshops.aws/workshops/a7011c82-e4af-4a52-80fa-fcd61f1dacd9/en-US/introduction) is a great next step.

 ## Tenets
 
 This project separates core utilities that will be available in other runtimes vs general utilities that might not be available across all runtimes.
