Installation of Shoutstats is pretty simple:

- Do some "tar zxvf shoutstats-*.tar.gz" in the directory you want shoutstats
  to be avalaible on the www (let's suppose it's /var/www/shoutstats)

- cd /var/www/shoutstats

- Edit the "config.php" so that Shoutstats can talk to your MySQL server

- Open the file "setup.php" in your favorite browser. It will create the
  required tables and provide you with an interface to add the shoutcast
  servers you want to monitor.

- Now you can start testing your installation by loading the file "update.php"
  in your browser. If everything is ok, you should see you server list with
  their current listeners and you should see the first listeners in shoutstats.

- You can now put the following line in your crontab:
  */5 * * * * /usr/bin/wget -q -O /tmp/update.php --delete-after http://your.host.com/shoutstats/update.php
  You can change the frequency, the more frequent the more precise your stats
  will be.
