Java JDK is the framework of the bot or its heart, it converts all the information given by the botclient to readable commands by your computer (the brains of the operation), without it your computer wouldn't know how to understand what the program is attempting to convey to it making it useless and not able to function correctly.

So you will need to download the latest version that has been released.

Now is the actual botting piece, the botclient downloaded in the second step is pre-installed with many different free commonly used scripts. Select the script by click on the middle play like button at the top right of the client or by going to file->run script.

The bot also has many other features including snapping to tray features which allow the bot to be completely out of your site so you can go about doing your business on your computer. It also has an automatic account login system. By entering your username into the client it will log in for you automatically when ever you are disconnected aswell as banking if you have a pin etc. The list goes on, but those are the basics more tutorials to come. Enjoy your botting!
