# Nickel **WARNING**: THIS CRATES IS ARCHIVED. This crate used to hold both the library and the binary for the Nickel configuration language, but `nickel-lang` had been split into the crates [`nickel-lang-cli`](https://crates.io/crates/nickel-lang-cli) containing the Nickel CLI (including the `nickel` binary) and [`nickel-lang-core`](https://crates.io/crates/nickel-lang-core) for the library exposing Nickel internals. - To install the `nickel` command, use `nickel-lang-cli`: `cargo install nickel-lang-cli` - To use Nickel as a dependency of your crate, use `nickel-lang-core`. All versions of `nickel-lang` will be yanked.
