 Let's convert Hello World to Cargo.

@@ -103,6 +105,62 @@ That's it! We've successfully built `hello_world` with Cargo. Even though our
 program is simple, it's using much of the real tooling that you'll use for the
 rest of your Rust career.
 
+## A New Project
+
+You don't have to go through this whole process every time you want to start a new
+project! Cargo has the ability to make a bare-bones project directory in which you
+can start developing right away.
+
+To start a new project with Cargo, use `cargo new`:
+
+```bash
+$ cargo new hello_world --bin
+```
+
+We're passing `--bin` because we're making a binary program: if we
+were making a library, we'd leave it off.
+
+Let's check out what Cargo has generated for us:
+
+```bash
+$ cd hello_world
+$ tree .
+.
+├── Cargo.toml
+└── src
+    └── main.rs
+
+1 directory, 2 files
+```
+
+If you don't have the `tree` command, you can probably get it from your distro's package
+manager. It's not necessary, but it's certainly useful.
+
+This is all we need to get started. First, let's check out `Cargo.toml`:
+
+```toml
+[package]
+
+name = "hello_world"
+version = "0.0.1"
+authors = ["Your Name <[email protected]>"]
+```
+
+Cargo has populated this file with reasonable defaults based off the arguments you gave
+it and your `git` global configuration. You may notice that Cargo has also initialized
+the `hello_world` directory as a `git` repository.
+
+Here's what's in `src/main.rs`:
+
+```rust
+fn main() {
+    println!("Hello, world!");
+}
+```
+
+Cargo has generated a "Hello World!" for us, and you're ready to start coding! A
+much more in-depth guide to Cargo can be found [here](http://doc.crates.io/guide.html).
+
 Now that you've got the tools down, let's actually learn more about the Rust
 language itself. These are the basics that will serve you well through the rest
-of your time with Rust.
