+Building the TigerVNC Server on Modern Unix/Linux Systems
+---------------------------------------------------------
+
 Building the TigerVNC Server (Xvnc) is a bit trickier.  On newer systems
 containing Xorg 7.4 or later (such as Fedora), Xvnc is typically built to use
 the X11 shared libraries provided with the system.  The procedure for this is
-very system-specific, since it requires specifying such things as font and X
-resource directories.  Thus, it cannot be described in terms general enough for
-this document.
+system-specific, since it requires specifying such things as font directories,
+but the general outline is as follows (this procedure assumes that the viewer
+has already been built, per above.)

+    (NOTE: {xorg_source} is the directory containing the Xorg source for the
+    machine on which you are building TigerVNC.  The most recent versions of
+    Red Hat/CentOS/Fedora, for instance, provide an RPM called
+    "xorg-x11-server-source", which installs the Xorg source under
+    /usr/share/xorg-x11-server-source.)
