+# Using HPVM
+The below benchmarks are provided with HPVM, along with a template Makefile for user projects. 
+
+In order to be able to build the existing benchmarks, a new `Makefile.config` must be created in [include](/hpvm/test/benchmarks/include) based on the existing `Makefile.config.example`. This configuration file must set up the following paths:
+* LLVM_BUILD_DIR: should point to your local `build` directory of HPVM.
+* HPVM_BENCH_DIR: should point to this benchmakrs directory.
+* CUDA_PATH: should point to your local CUDA installation.
