+## gosher -- A simple Gopher server in a POSIX shell script
 
 
-`gprsh` is a Gopher server in a shell script. It requires only a
-standard `netcat`. 
+`gosher` is a Gopher server in a POSIX shell script. It requires only a
+standard `netcat(1)`. 
 
 You start the server using:
 
-    $ ./gprsh [<PORT> [<GOPHERDIR>]
+    $ ./gosher [<PORT> [<GOPHERDIR>]
 
 If PORT is not specified, it will bind on port 70. If GOPHERDIR is not
 provided, it defaults to "./".
 
-`gprsh` reads the index.gph gopherfile in a folder and renders it as a
-gophermap. 
+If the selector is a directory, `gosher` will look for a file named
+`gophermap` to render the submenu. If a `gophermap` does not exist,
+`gosher` looks for the index.gph gopherfile in the folder and, if it
+exists, renders it as a gophermap.
+
+## Why `gosher`?
+
+Just for fun. There are only a few TCP/IP application protocols left
+that can be implemented in a few dozen lines of POSIX shell script, and
+Gopher (RFC 1436) is one of those. 
+
+## Why calling it `gosher`?
+
+Well, `gosher` is just `gopher` where the `p` is replaced with an `s`,
+and `sh(1)` is all that you need to run `gosher` (if we leave
+`netcat(1)` out...).
+
+Also, `gopher` is probably one of the few `kosher` protocols out there.
+
+According to the Urban Dictionary, `gosher` is "an insult that can mean
+anything", so choose your own.
