-Basic Configuration Examples for Spack Builds
-----------------------------------------------
-
-|br|
-Diverse Kokkos variants can be built / installed via Spack.  You will need to select a variant for the desired backend, and appropriate GPU microarchitecture.  To explore the range of variants for a package, ``spack info kokkos``, ``spack info trilinos``, etc.  Please see basic `Spack installation  <https://spack.readthedocs.io/en/latest/getting_started.html>`_ instructions if you're new to the package manager.

 Building and Linking a Kokkos "Hello World"
 -------------------------------------------
 
 .. note::
 
-  ``Kokkos_ROOT`` and the root directory for you target backend SDK (i.e., ``CUDA_ROOT``, ``ROCM_PATH``) will need to be set.  If a modules environment, the SDK variables will often be set upon module loading (e.g., ``module load rocm/5.7.1).  Please see `Build, Install and Use <https://kokkos.org/kokkos-core-wiki/building.html>`_ for additional details.
