Don't worry, Rustlings was made for beginners! We are -going to teach you a lot of things about Rust, but before we can get -started, here's a couple of notes about how Rustlings operates: - -1. The central concept behind Rustlings is that you solve exercises. These - exercises usually have some sort of syntax error in them, which will cause - them to fail compilation or testing. Sometimes there's a logic error instead - of a syntax error. No matter what error, it's your job to find it and fix it! - You'll know when you fixed it because then, the exercise will compile and - Rustlings will be able to move on to the next exercise. -2. If you run Rustlings in watch mode (which we recommend), it'll automatically - start with the first exercise. Don't get confused by an error message popping - up as soon as you run Rustlings! This is part of the exercise that you're - supposed to solve, so open the exercise file in an editor and start your - detective work! -3. If you're stuck on an exercise, there is a helpful hint you can view by typing - 'hint' (in watch mode), or running `rustlings hint myexercise`. -4. If an exercise doesn't make sense to you, feel free to open an issue on GitHub! - (https://github.com/rust-lang/rustlings/issues/new). We look at every issue, - and sometimes, other learners do too so you can help each other out! - -Got all that? Great! To get started, run `rustlings watch` in order to get the first -exercise.

The central concept behind Rustlings is that you solve exercises. These + exercises usually have some sort of syntax error in them, which will cause + them to fail compilation or testing.

This is part of the exercise that you're + supposed to solve, so open the exercise file in an editor and start your + detective work! +3. If you're stuck on an exercise, there is a helpful hint you can view by typing + 'hint' (in watch mode), or running `rustlings hint exercise_name`. +4. If an exercise doesn't make sense to you, feel free to open an issue on GitHub! + (https://github.com/rust-lang/rustlings/issues/new).
