First you need to download Le Bot here:

After that there's a tab on Le Bot called "Bot Mananger". Is there where the magic happens!
You can download any bot here, extract it from the .rar/.zip file and load it on the Bot Mananger.
Or, you can use one of the already made bots presents on Le Bot.
If you have one specific question, just ask it here.
