Thanks for installing Rustlings! Is this your first time? Let's make sure you're up to speed: - You have Rust installed, preferably via `rustup` - You have `~/.cargo/bin` added to your PATH variable - You have cloned this repository (https://github.com/rust-lang/rustlings) - You have installed Rust language support for your editor - You have locally installed the `rustlings` command by running: cargo install --path . If you've done all of this (or even most of it), congrats! You're ready to start working with Rust. To get started, run `rustlings watch` in order to get the first exercise. Make sure to have your editor open!
