+
+Remove Duplicates removes duplicate nodes
+according to any selected content field.
+
+This can be very useful with Drupal feeds module :
+- http://drupal.org/project/feeds
+
+This module was inspired by these threads : 
+- http://drupal.org/node/720190 : Remove Duplicate Nodes based on title
+- http://drupal.org/node/1211922 : remove duplicated node base on title problem
+
+THANKS
+------
+
+Thanks to dman <https://drupal.org/user/33240> for endorsing this project.
+
+He wrote a sandbox module "Deduplicate Nodes" for D6 intended to deduplicate
+nodes according to titles only : https://drupal.org/sandbox/dman/1422586
+
+INSTALLING
+----------
+
+See http://drupal.org/getting-started/install-contrib
+for instructions on how to install or update Drupal modules.
+
+Once Remove Duplicates is installed and enabled,
+you can use it at admin/config/content/remove_duplicates.
+
+It is highly recommended that you backup your database before using this module.
+
+UNINSTALLING
+------------
+
+Because Drupal does not uninstall modules in reverse 
+order of their dependencies, if you want to uninstall
+all the Remove Duplicates modules, be sure to disable 
+and uninstall all the sub-modules before the base Remove 
+Duplicates module.
+
+To help fix this bug in Drupal core, visit http://drupal.org/node/151452.
