What is it? Build an echo bot using the Discord API. Your bot will always respond with exactly what you send it for now.
What do you need to follow? A bit of Python experience is ideal, but you should be able to keep up even without it. You'll do everything from your browser so no Python set up is required. You can create a free account on Repl.it to save and share your code.
