 This library must be built with a F90 compiler, before LAMMPS is
 built, so LAMMPS can link against it.
 
+You can type "make lib-reax" from the src directory to see help on how
+to build this library via make commands, or you can do the same thing
+by typing "python Install.py" from within this directory, or you can
+do it manually by following the instructions below.

 Build the library using one of the provided Makefile.* files or create
 your own, specific to your compiler and system.  For example:
