+raytracer
+==============================================================================
+A follow-through of Peter Shirley's "Raytracing in X" series.
+
+Since this covers multiple different series, it is split up into the following
+subdirectories: `./rt1/` covers book 1 ("Raytracing In One Weekend"), `./rt2/`
+covers book 2 ("Raytracing The Next Week"), and `./rt3/` covers book 3
+("Raytracing The Rest Of Your Life").
+
+Written in relatively portable C99.
+
+raytracer: Building
+------------------------------------------------------------------------------
+To build, simply run `./build.sh`. To clean, similarly run `./clean.sh`.
+
+To build a specific book only, set the BOOK environment variable to the number
+of the book you want to build. For example, to build only book 1, run:
+`BOOK=1 ./build.sh`
