[support] newbie

Hi there. As I said I am newbie with Drupal but today I figured out how to install it and ready to go except now I have the welcome page " Welcome to your new Drupal website!" to start with and I guess I have to configure my website and so on. When I press any of those link it keeps showing me my apache welcome page. What am I missing? Mysql is up and running and php seems working. Any clue? Cheers Alfredo
