+Compiling
+---------
+
+* Windows (MSVC) - add lib/Remotery.c and lib/Remotery.h to your program. Set include
+  directories to add Remotery/lib path. The required library ws2_32.lib should be picked
+  up through the use of the #pragma comment(lib, "ws2_32.lib") directive in Remotery.c.
+
+* Mac OS X (XCode) - simply add lib/Remotery.c and lib/Remotery.h to your program.
+
+* Linux (GCC) - add the source in lib folder. Compilation of the code requires -pthreads for
+  library linkage. For example to compile the same run: cc lib/Remotery.c sample/sample.c
+  -I lib -pthread -lm
+
+You can define some extra macros to modify what features are compiled into Remotery. These are
+documented just below this comment.
