Print out files QUICKSTART, README and glow.txt
Copy all the files to a directory
Copy nrlmsise00.f and iri90.f to the directory or tell the compiler where they are
Copy the IRI data files to another directory
Rename the example program dayexample.driver to dayexample.f
Edit the IRI call in dayexample.f to specify the IRI data file directory
Compile and link *.f in Fortran 77 with -O3 optimization
Run the executable (a.out) with input from dayexample.in, i.e.:
  a.out < dayexample.in > test1.out
Compare the output you get to dayexample.out
If it looks reasonable, try making some plots
For auroral runs, change aurexample.driver to aurexample.f, compile, link, and:
  a.out < aurexample.in > test2.out
Compare the output you get to aurexample.out
Try some runs with your own input parameters
Now try making some modifications to the example program to suit your purposes

You can also run it all out of IDL using:
spawn, './a.out < input.file > output.file'

To perform high-energy aurora calculations:
  change the name of hexexample.driver to hexexample.f
  edit the glow.h file
     comment out the standard parameters
     comment in the high-energy parameters
  re-compile all subroutines, link, and:
  a.out < hexexample.in > test3.out
  compare to hexexample.out
