+# GNC: A Gemini Server for inetd
+
+GNC is a pure-Fortran implementation of a simple Gemini server for UNIX-like
+systems.  The server requires the inetd super-server (or compatible system
+like xinetd) to work.  GNC will handle all the TLS nonsense, and, if given a
+root directory to work with, should provide some mild security that only 
+files in that directory will be served (no promises, though!).
+
+## Requirements
+
+GNC requires almost nothing:
+
+ * A modern Fortran compiler (GNU Fortran > 7)
+ * OpenSSL
+ * The *file* command (for computing MIME types)
+ * inetd or equivalent (Debian calls it inetutils-inetd)
+
+There is a makefile provided to compile it (makefile.gnu) and a Simply
+Fortran project if you're rad.
+
+## Usage
+
+These directions will focus on just getting everything running on plain, old
+BSD-esque inetd.  Users can probably extrapolate for other systems.
+
+You'll first need to set up the Gemini protocol in the file /etc/services:
+
+```
+gemini		1965/tcp			# Gemini...
+```
+
+Next, you can add a nice line to inetd.conf:
+
+```
+gemini	stream	tcp	nowait	root	/path/to/gnc	gnc -pub /path/to/certs/cer
+t.pem -priv /path/to/certs/key.pem -root /path/to/files/to/serve -l /path/to/logfile
+```
+
+Note that if you don't provide a logfile (the "-l" option), GNC will write to
+/tmp/gnc.log all the time.
+
+The inetd.conf line above implies using *root* as the user for GNC which is super-
+unecessary.  Users should probably set up a sensible user instead.
+
+The "-root" option isn't mandatory.  If you don't provide it, though, GNC will just
+serve your **entire filesystem**, so maybe you should provide it...
+
+After that, it should just work.
+
+Paths ending in a slash will actually attempt to open a file "index.gmi" without
+letting the end user know.  You might want one of those in your root directory
+from which you're serving.
