+Contents:
+	1. Introduction
+	2. How to use
+
+THE CODE CONTAINS SOME CLEANUPS AND MINOR FIXES AFTER 18TH AUG. ALL THE TASKS WERE COMPLETED BEFORE 18TH.
+
+INTRODUCTION:
+
 The objective is to replace splay trees by a suitable data structure for 
 management of resident pages. Initial idea is to implement a radix tree like 
 data structure that will grow or shrink its height according to largest index 
 of the page inserted in to the object. There will be user-space implementation 
 of the tree first, which will be integrated in the kernel later on.
 
-UPDATE:
+
+HOW TO USE:
 
-User space implementation and test program in uspace/ 
-kernel source and new code in kern/
+There are three different parts
+	a. Radix tree implementation in userspace.
+	b. Splay Vs radix tree benchmarking.
+	c. Kernel integrated with radix tree.
 
-Memory is preallocated for radix nodes at the boot time. Currently the 
-both splay and radix trees are used in parallel with asserts on return 
-values. Once the integration is complete and tested the splay tree will be 
-removed.
+For a. and b. read the READMEs in uspace and uspace/benchmarking directories.
 
-Benchmarking is done, check the wiki page for updates.
-http://wiki.freebsd.org/MayurShardul/VM_Algorithm_Improvement
+To use the kernel follow instructions below.
+[You need FreeBSD 7.0 OS to use the kernel]
+1. go to kern/src directory.
+2. give following commands
+	2a. make buildkernel KERNCONF=GENERIC
+	2b. make installkernel
+3. Reboot
 
 
+Upon reboot you will boot modified kernel where radix tree is used for 
+management of resident pages instead of splay trees.
