Setup programming language for your bot

This is a quick list of all the requirements needed for all supported languages in which you can develop your bot.

Java

Install Java JDK. We officially support Java 8 but if you have a never version it should work as well.
Setup JAVA_HOME environment variable to point to the directory where you have installed Java JDK.

Python3

Install Python3 as instructed on the official site https://www.python.org/.
Make sure to add Python3 to path. On Windows there is a checkbox available when installing Python3.
On our servers your bun runs using Python3.6 so make sure your version is compatible with it.

Kotlin

The requirements are the same as for Java.
