 //-------------------------------------------------------
+// All options described below should be passed as a compiler flag to all files using Unity. If you must add #defines, place them BEFORE the #include above.
 
-// Integers
-//     - Unity assumes 32 bit integers by default
-//     - If your compiler treats ints of a different size, define UNITY_INT_WIDTH
+// Integers/longs/pointers
+//     - Unity assumes 32 bit integers, longs, and pointers by default
+//     - If your compiler treats ints of a different size, options are:
+//       - define UNITY_USE_LIMITS_H to use limits.h to determine sizes
+//       - define UNITY_INT_WIDTH, UNITY_LONG_WIDTH, nand UNITY_POINTER_WIDTH
 
 // Floats
 //     - define UNITY_EXCLUDE_FLOAT to disallow floating point comparisons
