	Welcome to the Microsoft Bot Builder generator v4.20.0.

	Detailed documentation can be found at https://aka.ms/botbuilder-generator

	? What's the name of your bot? my-chat-bot
	? What will your bot do? Demonstrate the core capabilities of the Microsoft Bot Framework
	? What programming language do you want to use? JavaScript     
	? Which template would you like to start with? Echo Bot - https://aka.ms/bot-template-echo
	? Looking good.  Shall I go ahead and create your new bot? Yes
	simplebot
	my-chat-bot
	Your bot should be in a directory named my-chat-bot
	I'll automatically create this folder.
