[INFO] [stdout] \u{1b}[H\u{1b}[2J\u{1b}[3JIs this your first time? Don\'t worry, Rustlings is made for beginners!
[INFO] [stdout] We are going to teach you a lot of things about Rust, but before we can
[INFO] [stdout] get started, here are some notes about how Rustlings operates:
[INFO] [stdout] 
[INFO] [stdout] 1. The central concept behind Rustlings is that you solve exercises. These
[INFO] [stdout]    exercises usually contain some compiler or logic errors which cause the
[INFO] [stdout]    exercise to fail compilation or testing. It\'s your job to find all errors
[INFO] [stdout]    and fix them!
[INFO] [stdout] 2. Make sure to have your editor open in the `rustlings/` directory. Rustlings
[INFO] [stdout]    will show you the path of the current exercise under the progress bar. Open
[INFO] [stdout]    the exercise file in your editor, fix errors and save the file. Rustlings will
[INFO] [stdout]    automatically detect the file change and rerun the exercise. If all errors are
[INFO] [stdout]    fixed, Rustlings will ask you to move on to the next exercise.
[INFO] [stdout] 3. If you\'re stuck on an exercise, enter `h` to show a hint.
[INFO] [stdout] 4. If an exercise doesn\'t make sense to you, feel free to open an issue on GitHub!
[INFO] [stdout]    (https://github.com/rust-lang/rustlings). We look at every issue, and sometimes,
[INFO] [stdout]    other learners do too so you can help each other out!
