 ```
-  export HIP_PATH=/opt/rocm/hip
-  export HCC_PATH=/opt/rocm/hcc
+  cd <your path>
+
+ - CLone roctracer and custom branches of HIP/HCC:
+  git clone -b amd-master https://github.com/ROCmSoftwarePlatform/roctracer.git
+  git clone -b roctracer-hip-frontend-180826 https://github.com/eshcherb/HIP.git
+  git clone --recursive -b roctracer-hip-frontend-180823 https://github.com/eshcherb/hcc.git
