Phew! Now that you've compiled, installed, and configured Eggdrop, it's time to start it up. Switch to the directory to which you installed the bot, cross your fingers, and type ./eggdrop -m <config> (where <config> is the name you gave to the config file). Eggdrop should start up, and the bot should appear on IRC within a few minutes. The -m option creates a new userfile for your bot. In future, you will only need to type ./eggdrop <config> to start the bot.
Once your bot is on IRC, it's important that you promptly introduce yourself to the bot. Msg it the 'hello' command you specified in the config file, e.g. /msg <botnick> hello. This will make you the bot's owner. Once that's done, you need to set a password using /msg <botnick> pass <password>. You can then DCC chat to the bot.
Now that your Eggdrop is on IRC and you've introduced yourself as owner, it's time to learn how to use your Eggdrop.
