  module load cudatoolkit
 
+If you will be using NetCDF, we suggest you add the following four lines to you ``.bashrc_ext`` file.
+
+::
+
+ module load cray-hdf5-parallel/1.12.2.9
+ module load cray-netcdf-hdf5parallel
+ export HDF5_DIR=/opt/cray/pe/hdf5-parallel/1.12.2.9
+ export NETCDF_DIR=/opt/cray/pe/netcdf-hdf5parallel/4.9.0.9

 Then build ERF as, for example (specify your own path to the AMReX submodule in ``ERF/Submodules/AMReX``):
 
 ::
 
- make -j 4 COMP=gnu USE_MPI=TRUE USE_OMP=FALSE USE_CUDA=TRUE AMREX_HOME=/global/u2/d/dwillcox/dev-erf/ERF/Submodules/AMReX
+ make -j 4 COMP=gnu USE_MPI=TRUE USE_OMP=FALSE USE_CUDA=TRUE AMREX_HOME=/path_to_here/ERF/Submodules/AMReX
+
