 Make sure you have an (MPI-aware) F90 compiler such as ``mpif90`` (e.g.
 Debian-ish machine: ``apt install openmpi-bin``, on an HPC cluster something
 like ``module load openmpi gcc``). Make sure to use the same compiler
 for QE and the extension. This should be the default case, but if problems
 arise you can manually select the compiler via
-``--f90exec=`` in ``build_total_energy_energy_module.sh``
+``--f90exec=`` in ``build_total_energy_module.sh``
 
 We assume that QE's ``configure`` script will find your system libs, e.g. use
 ``-lblas``, ``-llapack`` and ``-lfftw3``. We use those by default in
-``build_total_energy_energy_module.sh``. If you have, say, the MKL library,
+``build_total_energy_module.sh``. If you have, say, the MKL library,
 you may see ``configure`` use something like ``-lmkl_intel_lp64 -lmkl_sequential -lmkl_core``
 when building QE. In this case you have to modify
-``build_total_energy_energy_module.sh`` to use the same libraries!
