-# Compiling
+## Compiling
 This model was originally compiled and run with the intel16 compiler.
 It is recommended that you compile with an intel compiler.
 
 Compiling assumes that you have an intel compiler, MPI (impi, mpich,
 openmpi, etc), netcdf, and hdf5 in your LD_LIBRARY_PATH and LIBRARY_PATH.
+It is also assumed that nf-config and nc-config are in your path. 
 If you work on a machine with modules, you may need to load these 
 packages into your environment.
