 Since we want standard library to be thread-safe and [`std::sync`](https://doc.rust-lang.org/std/sync/) APIs to work, you'll need to use the nightly compiler toolchain and pass some flags to rebuild the standard library in addition to your own code.
 
-In order to reduce risk of breakages, it's strongly recommended to use a fixed nightly version. For example, the latest stable Rust at the moment of writing is version 1.66, which corresponds to `nightly-2022-12-12`, which was tested and works with this crate.

 ### Using config files
 
 The easiest way to configure those flags is:
 
-1. Put a string `nightly-2022-12-12` in a `rust-toolchain` file in your project directory. This tells Rustup to use nightly toolchain by default for your project.
