+1. TBBT Directory Structure
+
+# README: this file. Introduce the TBBT directory and how to use TBBT.
+# trace_init: source code for extract file system hierarchy from the trace
+# trace_play: source code for trace player
+# test: example of play the EECS Oct 21 1 hour trace. It contains the
+# original trace file: anon-lair62-011021-0000.txt
+# file system hierarchy map: fh-path-map-play
+# file system hierarchy: RFSFS
+#
+
+2. How to use TBBT?
+
+#STEP1: compile the TBBT player, change the executable "sfs3" to be owned
+# by root
+
+cd ~nzhu/TBBT/trace_play
+make sfs3
+su - root; chown root:root tplay; exit
+
+#STEP2: copy or link trace file in a directory for trace play
+
+cd TESTDIR
+ln -s ../test/anon-lair62-011021-0000.txt anon-lair62-011021-0000.txt
+
+#STEP3: extract the file system hierarchy from the trace file
+# There are two outputs: fh-path-map-play and RFSFS
+# fh-path-map-play is the file system hierarchy map
+# RFSFS is the actually file system hierarchy, instead of writing
+# each file to the full length, -S option creates a file system
+# hierarchy where all files are of 0 length. This is useful when
+# for experimental test run or debug run because writing all files
+# to the full length could be time consuming.
+
+~nzhu/TBBT/trace_init/extract-hierarchy anon-lair62-011021-0000.txt [-S]
+
+#STEP4: copy RFSFS to an exported directory on NFS file server
+
+scp -r RFSFS server:/export_dir/
+
+#STEP5: pair-up the request and reply packets in the trace.
+# The output file name is based on input file with suffix ".pair"
+# in this example, anon-lair62-011021-0000.txt.pair
+
+sfs3 -pair_trace anon-lair62-011021-0000.txt
+
+
+#STEP6: play the trace against initial file system hierarchy (RFSFS) on server
