 This repository is a fork of the official Rust programming
 language repository, created solely to verify the Rust standard

+Rust releases. The repository is tool agnostic and welcomes the addition of
 new tools.
 
 The goal is to have a verified [Rust standard library](https://doc.rust-lang.org/std/) and prove that it is safe.
 1. Contributing to the core mechanism of verifying the rust standard library
 2. Creating new techniques to perform scalable verification
 3. Apply techniques to verify previously unverified parts of the standard library.
 
-## [Kani](https://github.com/model-checking/kani)
+For that we are launching a contest that includes a series of challenges that focus on verifying
+memory safety and a subset of undefined behaviors in the Rust standard library.
+Each challenge describes the goal, the success criteria, and whether it has a financial award to be awarded upon its
+successful completion.
 
-The Kani Rust Verifier is a bit-precise model checker for Rust.
-Kani verifies:
-* Memory safety (e.g., null pointer dereferences)
-* User-specified assertions (i.e `assert!(...)`)
-* The absence of panics (eg., `unwrap()` on `None` values)
-* The absence of some types of unexpected behavior (e.g., arithmetic overflows).
+See [our book](https://model-checking.github.io/verify-rust-std/intro.html) for more details on the challenge rules
+and the list of existing challenges.
 
-You can find out more about Kani from the [Kani book](https://model-checking.github.io/kani/) or the [Kani repository on Github](https://github.com/model-checking/kani).
+We welcome everyone to participate!
