 This KMC_Lattice package implements several event recalculation options for creating computationally efficient simulations. 
 The package is designed to be usable on a personal computer and on high performance computing clusters.

 Most major planned features that are to be included in v2.0 are now implemented and have undergone preliminary testing. 
 However, this software tool is still under development, and as such, there may still be bugs that need to be squashed.

 This software tool uses [Message Passing Interface (MPI)](https://computing.llnl.gov/tutorials/mpi/) to utilize parallel computing power. 
 As a result, using KMC_Lattice requires that an MPI library is pre-installed on your system, and the final KMC_Lattice library must be built on your specific system. 
-We cannot provide pre-built binaries for your system. 
-Contact your HPC admin to determine the protocols for building MPI applications on your HPC system. 
-In many cases, the HPC system will already be configured for you, and the package comes with a default makefile that can be used with the [GCC compiler](https://gcc.gnu.org/) or the [PGI compiler](https://www.pgroup.com/).

+In many cases, the HPC system and environment will already be configured for you, and the package comes with a default makefile that can be used with the [GCC compiler](https://gcc.gnu.org/) or the [PGI compiler](https://www.pgroup.com/). 
 
 If you wish, you can also install MPI on your own personal workstation and then build the KMC_Lattice library there as well. For development and preliminary simulation tests, sometimes it is more efficient to run on your own workstation instead of an HPC system. More information about common MPI packages can be found here:
 - Open MPI, http://www.open-mpi.org/
 - MPICH, http://www.mpich.org/
 - MVAPICH, http://mvapich.cse.ohio-state.edu/
 
 Once you have an MPI library installed, to build the KMC_Lattice library, copy the KMC_Lattice directory to your machine, set it as your working directory, and run `make`. 
-Compilation flags have been set for GCC and PGI compilers.  If you are using another compiler, you will need to edit the makefile and define your own compiler options.
+Compilation flags have been set for the GCC and PGI compilers.  If you are using another compiler, you may need to edit the makefile and define your own compiler options.
 However, before you use the KMC_Lattice library, you should test it on your own hardware using the unit and system tests provided. 
 Build the testing executable by running `make test`. 
 Once the test build is complete, run `./test/KMC_Lattice_tests.exe`.
 Please report any build or testing errors in the [Issues](https://github.com/MikeHeiber/KMC_Lattice/issues) section.
