 ## Overview
 
-This repository provides the core infrastucture for using the succinct argument systems that arkworks provides. Users who want to produce arguments about various problems of interest will first reduce those problems to an NP relation, various examples of which are defined in the `ark-relations` crate. Then a SNARK system defined over that relation is used to produce a succinct argument. The `ark-snark` crate defines a `SNARK` trait that encapsulates the general functionality, as well as specific traits for various types of SNARK (those with transparent and universal setup, for instance). Different repositories within the arkworks ecosystem implement this trait for various specific SNARK constructions, such as [Groth16](https://github.com/arkworks-rs/groth16), [GM17](https://github.com/arkworks-rs/gm17), and [Marlin](https://github.com/arkworks-rs/marlin).
