-The **A**utomated **R**ate **C**alculator (**ARC**) software is a tool for automating
-electronic structure calculations and attaining thermo-kinetic data
-relevant for chemical kinetic modeling.
+**ARC** (Automated Rate Calculator) automates electronic structure calculations and extracts high-quality thermodynamic and kinetic data for use in chemical kinetic modeling.
 
-ARC has many <a href="https://reactionmechanismgenerator.github.io/ARC/advanced.html">advanced features</a>,
-yet at its core it is simple: It accepts 2D graph representations of chemical species (i.e.,
-<a href="https://en.wikipedia.org/wiki/Simplified_molecular-input_line-entry_system">SMILES</a>,
-<a href="https://www.inchi-trust.org/">InChI</a>,
-or <a href="https://rmg.mit.edu/">RMG</a>'s
-<a href="https://reactionmechanismgenerator.github.io/RMG-Py/reference/molecule/adjlist.html">adjacency list</a>),
-and  automatically executes, tracks, and processes relevant electronic structure calculation
-jobs on user-defined server(s). The principal outputs of ARC are thermodynamic properties
-(H, S, Cp) and high-pressure limit kinetic rate coefficients of species and reactions of interest.
+ARC has many [advanced features](https://reactionmechanismgenerator.github.io/ARC/advanced.html), but its core functionality is simple:
 
-## Mission
+> It takes 2D graph-based molecular representations—such as  
+> [SMILES](https://en.wikipedia.org/wiki/Simplified_molecular-input_line-entry_system), [InChI](https://www.inchi-trust.org/), or [RMG adjacency lists](https://reactionmechanismgenerator.github.io/RMG-Py/reference/molecule/adjlist.html)—and automatically executes, tracks, and processes the relevant electronic structure jobs on user-defined computing resources.
 
-ARC's mission is to provide the kinetics community with a well-documented and extensible codebase for automatically calculating species thermochemistry and reaction rate coefficients.
+ARC's key outputs are:
+- Thermodynamic properties (H, S, Cp)
+- High-pressure limit rate coefficients
