+Instructions
+============
+
+Edit the `Makefile`, commenting and uncommenting lines as required to match
+your compiler. Examples are provided that have been tested with GCC 7.3.0 and
+Clang 6.0.1 on FreeBSD 12.
+
+After the `Makefile` is configured, simply run `make clean run` to build and
+execute the program.
