 semantics, and uses colorized output to indicate which byte
 sequences go with which human-readable characters.
 
+uxd should compile and run on any modern POSIX-ish system. It's
+developed on Linux, and has been tested on Mac OS X. It's written in
+ANSI/ISO C89 and uses no libraries other than the standard C library.
+The Makefile should be compatible with any make utility (does not use
+GNU or BSD specific constructs).
+
+To install, use "make install" as root. This will put the binary
+in /usr/bin and the gzipped man page in /usr/man/man1. To adjust
+the install paths, use the standard make variables PREFIX, DESTDIR,
+BINDIR, DESTDIR, etc. See the top of the Makefile for the full list.
+Installation isn't required: the binary doesn't depend on any other
+files at runtime, and can just be copied somewhere on your $PATH.

 See uxd.rst for full documentation, or (after installation), "man uxd".
