+## COMPILE

+Though this project do has a .vcxproj file,  
+you can only edit but not compile in visul studio.  
+Currently you can only compile this lib via Clang and cmake.
+
+## Code Layout
 
 Conventions:
+
 - src/        : project C sources and CMakeLists.txt calling add_library/add_executable
 - include/    : public headers (if used)
 - external/   : third-party libraries, each library lives in its own folder
-    - <libname>/
+    - libname/
         - head/   : header files for the library
         - lib/    : static or shared lib files (or CMake build for that lib)
