[Koha] Default Intranet/Opac Cardnumber and password

Hi All, Am greatful that I was able to succefully download and Install KOHA 2.2.8. Have been able to load the Intranet and Opac pages on my browser, However, I don't have the cardnumber and password to enable me to login. Are there default cardnumbers and passwords for Intranet/OPAC login to enable me login and is there a documentation for Koha 2.2.8.? Please help. Rgds Isaac Kimani Asst.
