A bot is nothing more than a lot of scripts put together on a an extra client. All tutorials will help you to add scripts to do what you need into the bot. That's how you make a bot.
For example, if you want the bot to prevent floods, go look up a flood protection tutorial and add a script for flood protection into the bot. If you want it to send a !help file to someone, or just respond with text to a trigger like that, look up tutorials about ON TEXT or DCC SEND. And, of course, the help file is a great resource.
