+Before installing HPVM, some paths must be set for installation to succeed. The following variables in set_paths.sh must be set:
+
+* CUDA_TOOLKIT_PATH --- Path to the CUDA toolkit
+* CUDA_INCLUDE_PATH --- Path to the CUDA headers
+* CUDA_LIB_PATH -- Path to CUDA libraries 
+
+Once the aforementioned variables in set_paths.sh have been specified, run the script.
+```shell
+source set_paths.sh
+```
+
 HPVM installer script can be used to download, configure and build HPVM along with LLVM and Clang. 
 ```shell
 bash install.sh

hpvm/set_paths.sh

+#!/bin/bash
+
+# These paths can be modified by the HPVM user
+CUDA_TOOLKIT_PATH=cuda-toolkit/9.1
+CUDA_INCLUDE_PATH=/software/cuda-9.1/include
