+I originally created this software in 2013 using AutoIt. After learning Java, I recreated it in Java. The original
+version can be found at: https://archive.knarcraft.net/Scripts/BungeeMinecraftServerLauncher/
 This version's goal is to do everything the original does, just better. The original is 1595 lines of code repetition
 and dirty code. I had no prior programming experience when I first started working on the original, which is why it
 became such a mess.
 
-The software is in a fully working stage with a functional updater. The software is still in beta because there are still
-a lot of things I want to change and small annoyances. The software is fully portable. Make sure to put it in its own
-folder as it will create lots of files.

-The updater will move the new version to minecraft-server-launcher.jar, so you should rename the downloaded
-file to this if it's named something else to avoid confusion.
