 ## Introduction
 
 Implementation of the high-fidelity model of granular media that combines the advantages 
-of peridynamics and discrete element method (DEM). 
+of peridynamics and the discrete element method (DEM). 
 The model has the following advantages over existing mechanical models for granular media:
   - handle intra-particle deformation and breakage/damage
-  - handle arbitrary shape of the particle. Inter-particle contact is not specific to any shape of the particle
+  - handle the arbitrary shape of the particle. Inter-particle contact is not specific to any shape of the particle
   - tunable inter-particle contact parameters
   - easy to add different mechanical constitutive laws within peridynamics for individual particle deformation
