+# Student Source Files
+####################################################################
+
+This directory contains the files you will need for the CS:APP Proxy
+Lab.
+
+proxy.c
+csapp.h
+csapp.c
+    These are starter files.  csapp.c and csapp.h are described in
+    your textbook. 
+
+    You may make any changes you like to these files.  And you may
+    create and handin any additional files you like.
+
+    Please use `port-for-user.pl' or 'free-port.sh' to generate
+    unique ports for your proxy or tiny server. 
+
+Makefile
+    This is the makefile that builds the proxy program.  Type "make"
+    to build your solution, or "make clean" followed by "make" for a
+    fresh build. 
+
+    Type "make handin" to create the tarfile that you will be handing
+    in. You can modify it any way you like. Your instructor will use your
+    Makefile to build your proxy from source.
+
+port-for-user.pl
+    Generates a random port for a particular user
+    usage: ./port-for-user.pl <userID>
+
+free-port.sh
+    Handy script that identifies an unused TCP port that you can use
+    for your proxy or tiny. 
+    usage: ./free-port.sh
+
+driver.sh
+    The autograder for Basic, Concurrency, and Cache.        
+    usage: ./driver.sh
+
+nop-server.py
+     helper for the autograder.         
+
+tiny
+    Tiny Web server from the CS:APP text
+
