	# Usage Instructions
	First, paste a valid USACO (https://usaco.org) or codeforces (https://codeforces.com) problem link into the first text box input.
	Then, paste the link to an official editorial for the problem. 

	Choose between either 'hint' mode or 'editorial' mode


	## Hint Mode
	Chat with the bot about your ideas to solve the problem, and it will give you hints to guide your thinking.


	## Editorial Mode
	Get a simplified summary with step-by-step observations to solve the problem, and chat with the bot about questions you have about the editorial.

	# Feedback
	Please provide written feedback, maybe there was an issue with the bot or you really liked some response. You can give written feedback while chatting with the bot; it is recorded in real time with the chat history. Use the second text box for this.
	Please also provide feedback on the bot's helpfulness. Use the first dropdown (after you completed your chat) to rate how helpful the bot was. Consider how the bot's responses helped your understand faster and more effectively.
	
	Thanks for using this bot, and I hope you found it helpful!
