+
+This RT extension adds a "Merge Users" box to the User Administration page, 
+which allows you to merge the user you are currently viewing with another
+user on your RT instance.  It also adds MergeInto() and Unmerge() functions to 
+the RT::User class, which allow you to programmatically accomplish the same
+thing from your scrips.  It also provides a version of CanonicalizeEmailAddress,
+which means that all e-mail sent from secondary users is displayed as coming
+from the primary user.
+
+To install:
+
+    perl Makefile.PL
+    make install
+
+For 3.8
+
+    Add RT::Extension::MergeUsers to your /opt/rt3/etc/RT_SiteConfig.pm file
+    Set(@Plugins, qw(RT::Extension::MergeUsers));
+
+UPGRADING
+
+If you are upgrading from 0.03_01 or earlier, you must run rt-upgrade-merged-users
+This script will create MergedUsers Attributes so RT can know when you're looking
+at a user that other users have been merged into.  If you don't run this script,
+you'll have issues unmerging users.  It can be safely run multiple times, it will
+only create Attributes as needed.

+-------------------------------------------------------------------------------
+
+Since you are using Microsoft Windows, you will need the 'nmake' utility
+before installation. It's available at:
+
+  http://download.microsoft.com/download/vc15/Patch/1.52/W95/EN-US/Nmake15.exe
+      or
+  ftp://ftp.microsoft.com/Softlib/MSLFILES/Nmake15.exe
+
+Please download the file manually, save it to a directory in %PATH% (e.g.
+C:\WINDOWS\COMMAND\), then launch the MS-DOS command line shell, "cd" to
+that directory, and run "Nmake15.exe" from there; that will create the
+'nmake.exe' file needed by this module.
+
+You may then resume the installation process described in README.
