 Compile Programs with Rabit
 ---------------------------
 Rabit is a portable library, to use it, you only need to include the rabit header file.
-* You will need to add the path to [../include](../include) to the header search path of the compiler
+* You will need to add the path to [../include](https://github.com/dmlc/rabit/blob/master/include) to the header search path of the compiler
   - Solution 1: add ```-I/path/to/rabit/include``` to the compiler flag in gcc or clang
   - Solution 2: add the path to the environment variable CPLUS_INCLUDE_PATH
-* You will need to add the path to [../lib](../lib) to the library search path of the compiler
+* You will need to add the path to [../lib](https://github.com/dmlc/rabit/blob/master/lib) to the library search path of the compiler
   - Solution 1: add ```-L/path/to/rabit/lib``` to the linker flag
   - Solution 2: add the path to environment variable LIBRARY_PATH AND LD_LIBRARY_PATH
 * Link against lib/rabit.a
