-put something here
+The Tokutek Fractal Tree Engine library is not publicly available software. 
+This software product is Tokutek commercial software and use of this software
+is governed by your applicable license agreement with Tokutek.
+
+Fractal Tree Index Library
+
+The Fractal Tree Index software is provided as a shared library called
+"libtokufractaltreeindex-RELEASE.so".
+
+Installation
+
+Copy "libtokufractaltreeindex-RELEASE.so" to some place that the library 
+loader uses to find libraries.
+
+For example, on Centos 5, 64 bit libraries are found in /usr/lib64. Installation
+is as simple as executing the following:
+    sudo cp libtokufractaltreeindex-RELEASE.so /usr/lib64
+          
+Some users put it into "/usr/mysql/lib" because some useful binaries 
+that employ the library include "/usr/mysql/lib" in their rpath.
+          
+Some users put it into /opt, for example in "/opt/tokutek/lib". In this 
+case you will need to arrange for the loader to be able to find it 
+(e.g., by arranging that LD_LIBRARY_PATH includes /opt/tokutek/lib).
+
+If you do not have root access you can put it into a directory in your home directory.  You may need to help the loader find it, using something like:
+   mkdir ~/lib
+   cp libtokufractaltreeindex-2.1.0-15000.so ~/lib/
+   export LD_LIBRARY_PATH=~/lib/
+
+Examples
+
+To use the Fractal Tree index as an embedded database, please read the
+README.examples file in the examples directory.
