+REINSTALL
+------------
+
+Drupal can be reinstalled without downloading and extracting the Drupal release.
+
+1. Drop all the tables in your database.
+
+2. Remove everything in sites/default/files.
+
+3. Remove sites/default/settings.php then create a new one using the file
+   sites/default/default.settings.php as a template.
+
+   For example, on a Unix/Linux command line, you can make a copy of the
+   default.settings.php file with the command:
+
+      cp sites/default/default.settings.php sites/default/settings.php
+
+   Next, grant write privileges to the file to everyone (including the web
+   server) with the command:
+
+      chmod a+w sites/default/settings.php
+
+   Be sure to set the permissions back after the reinstallation is finished!
+   Sample command:
+
+      chmod go-w sites/default/settings.php
+
+4. Follow the Installation Instructions above starting from Step 3 (Run the
+   install script).
