+### Spack
+
+
+The project supports building with Spack >= 0.19.0, which can be installed without root via the [official GitHub repo](https://github.com/spack/spack).
+The BabelStream Spack Package source code could be accessed from the link [here](https://github.com/spack/spack/tree/develop/var/spack/repos/builtin/packages/babelstream/package.py)
+Each BabelStream implementation (programming model) is built as follows:
+
+```shell
+
+# Spack package installation starts with `spack install babelstream` for all programming models
+# The programming model wish to be build needs to be specified with `+` option
+# The model specific flags needs to be specified after defining model
+$ spack install babelstream@<version>%<compiler> +<model> <model specific flags>
+
+
+# The executables will be generated in:
+# SPACK_INSTALL_DIRECTORY/opt/spack/system-name/compiler-name/babelstream-version-identifier/bin/
+# this address will be printed at the end of generation which could be easily copied
+$ cd SPACK_INSTALL_DIRECTORY/opt/spack/system-name/compiler-name/babelstream-version-identifier/bin/
+$ ./<model>-stream
+```
+More detailed examples are provided in [Spack README file]()
+The `MODEL` option selects one implementation of BabelStream to build.
+
+Currently available models are:
+```
+omp;ocl;std;std20;hip;cuda;kokkos;sycl;sycl2020;acc;raja;tbb;thrust
+```

 ### GNU Make
 
 Support for Make has been removed from 4.0 onwards.

+## OpenMP
+
+* There are 3 offloading options for OpenMP: NVIDIA, AMD and Intel. 
+* If a user provides a value for `cuda_arch`, the execution will be automatically offloaded to NVIDIA.
+* If a user provides a value for `amdgpu_target`, the operation will be offloaded to AMD.
+* In the absence of `cuda_arch` and `amdgpu_target`, the execution will be offloaded to Intel.
