 CS498-MS Project - Radix Sort with MPI and OpenMP
 =================================================
 
-Requirements:
+### Requirements
 * cmake 3.1+
 * Compiler with C++11 and OpenMP support
 * MPI-3.0 implementation
 
-To compile:
+### Compilation

 mkdir build
 cd build

 The cmake command can be supplied options to determine the build type
 (optimization level), compiler flags, and compiler.
 
+### Datasets
 There are three datasets generated:
-* A. uniformly distributed between 0 and 2^31 - 1
-* B. normally distributed with a mean of 2^30 and a stddev of 2^20
-* C. uniformly distributed between 0 and 255
-For each of these, the array size is varied between 2^16 and 2^24.
+* A. uniformly distributed between $`0`$ and $`2^{31} - 1`$
+* B. normally distributed with a mean of $`2^{30}`$
+     and a standard deviation of $`2^{20}`$
+* C. uniformly distributed between $`0`$ and $`255`$
+
+For each of these, the array size is varied between $`2^{16}`$ and $`2^{24}`$.
 
 The data directory contains output tables from single-node runs
 of both the MPI and OpenMP versions, scaling from 1 to 16 processors
