 # Demo for CMake package usage
 
 This folder demonstrates how to use eventpp as CMake package.  
-To build the demo program,  
-
-1, Install eventpp as CMake package
-
-1.1, Install eventpp locally.  
-
-In eventpp root folder, run the commands,  
-```
-mkdir build
-cd build
-cmake ..
-sudo make install
-```
-
-2, Then  
-
-```
-mkdir build
-cd build
-cmake .. -G"MinGW Makefiles"
-mingw32-make.exe
-```
-
-If you use other making system rather than MingW, replace the -G generator and mingw32-make.
+See the project readme.md for how to build the demo program.
