This guide covers preparing for installation, running the installation script, and the steps that should be done after the installation script has completed. It also explains how to do a "multi site" installation, where a number of different Drupal sites run off the same code base.
This documentation focuses on performing tasks at the command line. For information on using graphical tools, see the documentation that accompanies the application or is provided by your hosting service. Some web hosting companies also offer "one-click" installations of Drupal, or specific Drupal support.
There is also information about Drupal distributions, which include installation profiles and pre-packaged distributions of Drupal and modules. These may be of help as well.
If you encounter difficulties, you can refer to the Troubleshooting Guide.
