 [baud.c](baud.c) is a program to simulate going through a modem.
 It reads stdin, and prints it to stdout at the provided baud rate (bits per second).
 
+
+Building
+--------
+
+Download [baud.c](baud.c). Change to that directory, and type
+
+    make baud
+
+That will generate a file named `baud` in whatever directory you're in.
+If you like,
+you can put it in `~/bin` or `~/.local/bin` or `/usr/games/bin` or
+wherever you prefer.
+
+
+Running
+-------
+
 If you'd like to see what life was like when I got my first modem, try
 
-    cat file | ./baud.c 110 40
+    cat file | ./baud 110 40
 
 Run that for a few hours, then try
 
-    cat file | ./baud.c 1200 20
+    cat file | ./baud 1200 20
 
 And you will understand how mind-blowingly fast 1200 baud modems were at the time.
 
+    frotz zork1.zip | ./baud 4800
+
+Gives Zork a retro vibe,
+without being so slow that it's aggravating.
+I don't think more than a dozen or so people every played Zork over a modem link,
+but whatever.
+
+
+Why
 ---
 
-This is the second or third time I've written this code.
+Every 10 years or so, somebody asks me for this program.
+I don't know why.
+
+The other day it happened again, and I couldn't find it soon enough,
+so I just wrote it again from scratch.
 I'm putting it on my web site so I don't have to write it again.
