 ## Getting source code and building HPVM
 
 Checkout HPVM:
 ```shell
-git clone --recursive https://gitlab.engr.illinois.edu/llvm/hpvm-release.git/
-cd hpvm-release/hpvm
+git clone --recursive https://gitlab.engr.illinois.edu/llvm/hpvm.git

 HPVM needs to be able to find CUDA.

 Specifically, the HPVM installer downloads LLVM, and Clang, copies HPVM source into 
 llvm/tools and builds the entire tree. It also builds a modified LLVM C-Backend, based on the one maintained by [Julia Computing](https://github.com/JuliaComputing/llvm-cbe), as a part of HPVM and is currently used 
 to generate OpenCL kernels for GPUs.
