The darker blue boxes on the left represent commands, and the lighter blue boxes are responses. The command is what a user will type in the server to trigger the responses that are connected to it. For example, if a user types !help (assuming the prefix is !), then the "help menu" response will be triggered. You can connect any number of response to a command. If you run the bot with these default commands, you can test them out in a server to get a feel for how they work.
