 The `#[tokio::main]` at the beginning of this example is a Tokio macro necessary because Goose is an asynchronous library, allowing (and requiring) us to declare the `main()` function of our load test application as `async`.
 
-If you're new to Rust, `main()`'s return type of `Result<(), GooseError>` may look strange. It essentially says that `main` will return nothing (`()`) on success, and will return a `GooseError` on failure. This is helpful as several of `GooseAttack`'s methods can fail, returning an error. In our example, `initialize()` and `execute()` each may fail. The `?` that follows the method's name tells our program to exit and return an error on failure, otherwise continue on. Note that the `.execute()` method is asynchronous, so it must be followed with `.await`, and as it can return an error it alsos has a `?`. The final line, `Ok(())` returns the empty result expected on success.

 And that's it, you've created your first load test! Read on to see how to run it and what it does.
