-Use following instruction to build.
+You need have your boost unpacked on your disk, at least staged following modules:
+
+* system
+* date_time
+* random
+* unit_test_framework
+
+Then use following instruction to gen makefile or VS project.
 ```bash
-cmake -DBOOST_LIB=`<your boost static libs path>` -DBOOST_INCLUDE`<your boost include path>` -DBOOST_VER:STRING=`<your boost version>` -DCMAKE_BUILD_TYPE=Debug ./
-```
+cmake -DBOOST_LIB=`<your boost static libs path>` -DBOOST_INCLUDE=`<your boost include path>` -DBOOST_VER:STRING=`<your boost version>` -DCMAKE_BUILD_TYPE=Debug ./
+```
+Then run `make` or open by VS.
+
+For example I've installed boost 1.57.0 at `D:\boost_1_57_0` and staged the static lib at `D\boost_1_57_0\build\lib` then the command should be:
+```bash
+cmake -DBOOST_LIB=D:\boost_1_57_0\build\lib -DBOOST_INCLUDE=D:\boost_1_57_0 -DBOOST_VER:STRING=1.57.0 -DCMAKE_BUILD_TYPE=Debug ./
+```
+In this case(Windows) CMake will create a VS project under `./test` folder. Open in VS and run it.
