// IMPORTANT: Most users of Ceres will not use this file, when compiling Ceres
// with CMake, CMake will configure a new config.h with the currently
-// selected Ceres compile options and copy it into the source
-// directory before compilation. However, for some users of Ceres
-// who compile without CMake, this file ensures that Ceres will
-// compile, with the user either specifying manually the Ceres
+// selected Ceres compile options in <BUILD_DIR>/config, which will
+// be added to the include path for compilation, and installed with
+// with the public Ceres headers. However, for some users of Ceres
+// who compile without CMake (Android), this file ensures that Ceres
+// will compile, with the user either specifying manually the Ceres
// compile options, or passing them directly through the compiler.
