Drupal is available in two supported versions (the most recent and the previous). The "recommended release" is the latest stable release of that version. To learn more about versions, see the Drupal version information page.

If you would like to create a Drupal site in a language other than English, information about Drupal translations is available at http://localize.drupal.org/translate.
Downloading Drupal

Note: Since 8.x, Drupal can create the database itself if its database user has enough privileges. See the relevant change notice.

Before running the installation script, you must create an empty database and database user (a user name assigned the rights to use the Drupal database).

Step 3 in my opinion is the most important!

Prior to running the installation script, you must create a settings.php file and set some permissions.
Settings.php

Your Drupal download comes with a sample configuration file at sites/default /default.settings.php. The default file must be copied and the new file must be given the correct name, settings.php.
