Hello World

Let’s first set up a Rust project with S-two. 
$ cargo new stwo-example
We need to specify the nightly Rust version to use S-two. 
$ echo -e "[toolchain]\nchannel = \"nightly-2025-01-02\"" > rust-toolchain.toml
Now let’s edit the Cargo.toml file as follows: 
[package]
name = "stwo-examples"
version = "0.1.0"
edition = "2021"
license = "MIT"

[dependencies]
stwo = { git = "https://github.com/starkware-libs/stwo.git", rev = "75a6b0ac9bcc7101d8658445dded51923ab2586f", features = ["prover"]}
stwo-constraint-framework = { git = "https://github.com/starkware-libs/stwo.git", rev = "75a6b0ac9bcc7101d8658445dded51923ab2586f", package = "stwo-constraint-framework", features = ["prover"] }
num-traits = "0.2.17"
itertools = "0.12.0"
rand = "0.8.5"
We are all set!
