 The Quarkus stack is designed to provide a foundation for building and running Java applications on Quarkus with Appsody.
 
-This stack is based on the `Quarkus 1.5.0.Final` runtime. It allows you to develop new or existing Java applications that run on Quarkus and can be turned into a native executable for a low memory footprint and near instantaneous (< 10ms) start times.
