## Usage

This repository contains the [halo2_proofs](halo2_proofs/README.md) and

[halo2_gadgets](halo2_gadgets/README.md) crates, which should be used directly.

## Minimum Supported Rust Version

Requires Rust **1.60** or higher.

Minimum supported Rust version can be changed in the future, but it will be done with a

minor version bump.

## Controlling parallelism

`halo2` currently uses [rayon](https://github.com/rayon-rs/rayon) for parallel computation.

The `RAYON_NUM_THREADS` environment variable can be used to set the number of threads.

You can disable `rayon` by disabling the `"multicore"` feature.

Warning! Halo2 will lose access to parallelism if you disable the `"multicore"` feature.

This will significantly degrade performance.
