+# engine source
+
+This folder contains the crêpe engine source files, unit tests, and some toy
+examples. The only target built by default by the CMakeLists.txt in this folder
+is the crêpe shared library object. Unit tests can be built by explicitly
+specifying the target `test_main` when running the build command. Each source
+file in the example/ folder corresponds to a CMake target as well.
