+LAMMPS and LAMMPS GUI universal binaries for macOS (arm64/x86_64)
+=================================================================
+
+This package provides universal binaries of LAMMPS and LAMMPS GUI that should
+run on macOS systems running running macOS version 11 (Big Sur) or newer.  Note
+the binaries are compiled without MPI support and contain a compatible subset
+of the available packages.
+
+The following individual commands are included:
+binary2txt lammps-gui lmp msi2lmp phana stl_bin2txt
+
+After copying the lammps-gui folder into your Applications folder, please follow
+these steps:
+
+1. Open the Terminal app
+
+2. Type the following command and press ENTER:
+
+   open ~/.zprofile
+
+   This will open a text editor for modifying the .zprofile file in your home
+   directory. 
+
+3. Add the following lines to the end of the file, save it, and close the editor
+
+   LAMMPS_INSTALL_DIR=/Applications/lammps-gui.app/Contents
+   LAMMPS_POTENTIALS=${LAMMPS_INSTALL_DIR}/share/lammps/potentials
+   LAMMPS_BENCH_DIR=${LAMMPS_INSTALL_DIR}/share/lammps/bench
+   MSI2LMP_LIBRARY=${LAMMPS_INSTALL_DIR}/share/lammps/frc_files
+   PATH=${LAMMPS_INSTALL_DIR}/bin:$PATH
+   export LAMMPS_POTENTIALS LAMMPS_BENCH_DIR PATH
+
+4. In your existing terminal, type the following command make the settings active
+
+   source ~/.zprofile
+
+   Note, you don't have to type this in new terminals, since they will apply
+   the changes from .zprofile automatically.
+
+5. Try running LAMMPS
+
+   lmp -in $LAMMPS_BENCH_DIR/in.lj
+
+6. Try running LAMMPS GUI
+
+   lammps-gui $LAMMPS_BENCH_DIR/in.rhodo
