+      Micronaut is a modern, JVM-based, full stack microservices framework
+      designed for building modular, easily testable microservice applications.
       Reflection-based IoC frameworks load and cache reflection data for 
       every single field, method, and constructor in your code, whereas with 
       Micronaut, your application startup time and memory consumption are 
       not bound to the size of your codebase.
