# Kotlin IntelliJ IDEA Environment Setup
The free Community Edition of IntelliJ IDEA can be downloaded from: [https://www.jetbrains.com/idea/download/index.html](https://www.jetbrains.com/idea/download/index.html)
After downloading and installing, we can use this tool to create a project. During the creation process, you need to select an SDK. Kotlin works with JDK 1.6+.
Check the Kotlin (Java) checkbox in the dropdown menu on the right.

Now, let's add a line of code to print "Hello, World!".

Next, we can run the code by clicking the Kotlin icon in the top-left corner of the editor and selecting 'Run 'AppKt'':

After a successful run, you can see the result in the 'Run' window.

This way, our first Kotlin code is up and running.
