 1. Clone from github
 
    ```bash
-   git clone https://github.com/cupbop/CuPBoP
+   git clone https://github.com/drcut/CuPBoP
    cd CuPBoP
    export CuPBoP_PATH=`pwd`
    export LD_LIBRARY_PATH=$CuPBoP_PATH/build/runtime:$CuPBoP_PATH/build/runtime/threadPool:$LD_LIBRARY_PATH

-   If you are using boson, you can pre-installed llvm 10.0.0\
-   `LLVM_PATH=/opt/llvm-10.0.0`\
-   `export PATH=$LLVM_PATH/bin:$PATH`
