-ARC automates quantum chemical calculations and calculates thermodynamic properties and kinetic rates from 2D representations of species.
+**ARC - Automated Rate Calculator** is a software for automating
+electronic structure calculations relevant for chemical kinetic modeling.
+ARC has many advanced options, yet at its core it is simple: it accepts 2D
+graph representations of chemical species (e.g., SMILES or adjacency lists),
+and  automatically executes, tracks, and processes relevant electronic structure
+jobs on user-defined servers. The principal outputs of ARC are thermodynamic properties
+(H, S, Cp) and high-pressure limit kinetic rate coefficients for the defined species
+and reactions.
+(Note that automating transition states is still in progress).
