-Thanks for installing Rustlings!
-
-Is this your first time? 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. Make sure to have your editor open!
