Mildly confusing line in getting_started_step_1

[bronson]

In getting_started_step_1, the instructions say to "add the following four lines to the top of src/lib.rs". Following this literally results in an uncompilable file:

#![feature(proc_macro)]

#[macro_use] extern crate diesel_codegen;

pub mod schema;
pub mod models;

#[macro_use] extern crate diesel;
extern crate dotenv;

#[macro_use] extern crate diesel; needs to come before #[macro_use] extern crate diesel_codegen; of course.

I'd submit a PR to add some wording but I didn't see where the getting-started file was located.

This didn't take long to figure out, just hoping to save others the trouble.

And the error is pretty darned confusing:

error: `#[derive]` for custom traits is not stable enough for use. It is deprecated and will be removed in v1.15 (see issue #29644)
 --> src/models.rs:1:10
  |
1 | #[derive(Queryable)]
  |          ^^^^^^^^^
  |
  = help: add #![feature(custom_derive)] to the crate attributes to enable

error: aborting due to previous error

error: Could not compile `diesel_demo`.

Same thing with src/models.rs in step 2, "We'll want a struct to use for inserting a new record." It's not clear that the new code should integrate with the existing.

@bronson sorry for the short but still delayed answer; you can find the getting started code at https://github.com/diesel-rs/diesel/tree/master/examples and the website text at https://github.com/sgrif/diesel.rs-website

Thank you, I'll submit PRs there.
