 ## Ready-to-code Dev Environments for Java
 
-In order to setup your project, you should run `gp init` in the terminal first. This will create the two configuration files needed to explain Gitpod what your project needs.

 ### SDKMAN
 
-For Java it comes ready equipped with [SDKMAN!](https://sdkman.io/), which is a version manager that takes care of managing and installing not only different Java versions, but also different version of other JVM langauges such as Scala or Kotlin (both suppoeted in Gitpod, too).

 It also installs Maven and Gradle in case you don't use the [wrapper version](https://docs.gradle.org/current/userguide/gradle_wrapper.html) that is often recommended.
 
 Check out the [documentation of SDKMAN!](https://sdkman.io/usage) to see how to use it or simply type `sdk help` in the terminal.
