+# Getting started
+
+## Install nightly Rust
+
+Maud requires the nightly version of Rust.
+If you're using `rustup`,
+see the [documentation][rustup]
+for how to install this version.
+
+[rustup]: https://github.com/rust-lang/rustup.rs/blob/master/README.md#working-with-nightly-rust
+
+## Add Maud to your project
+
+Once Rust is set up,
+create a new project with Cargo:
+
+```sh
+cargo new --bin pony-greeter
+cd pony-greeter
+```
+
+Add `maud` to your `Cargo.toml`:
+
+```toml
+[dependencies]
+maud = "*"
+```
+
+Then save the following to `src/main.rs`:
+
+```rust
+#![feature(proc_macro_hygiene)]
+
+extern crate maud;
+use maud::html;
+
+fn main() {
+ let name = "Lyra";
+ let markup = html! {
+ p { "Hi, " (name) "!" }
+ };
+ println!("{}", markup.into_string());
+}
+```
+
+`html!` takes a single argument: a template using Maud's custom syntax. This call expands to an expression of type [`Markup`][Markup], which can then be converted to a `String` using `.into_string()`.
+
+[Markup]: https://docs.rs/maud/*/maud/type.Markup.html
+
+Run this program with `cargo run`, and you should get the following:
+
+```
+<p>Hi, Lyra!</p>
+```
+
+Congrats – you've written your first Maud program!

+ h1 { "Hello, world!" }
+ p.intro {
+ "This is an example of the "
+ a href="https://github.com/lfairy/maud" { "Maud" }
+ " template language."
+ }
+}
+```
+
+Maud is an HTML [template engine] for Rust. It's implemented as a macro, `html!`, which compiles your markup to specialized Rust code. This unique approach makes Maud templates blazing fast, super type-safe, and easy to deploy.
+
+[template engine]: https://www.simple-is-better.org/template/
+
+## Tight integration with Rust
+
+Since Maud is a Rust macro, it can borrow most of its features from the host language. Pattern matching and `for` loops work as they do in Rust. There is no need to derive JSON conversions, as your templates can work with Rust values directly.
+
+## Type safety
+
+Your templates are checked by the compiler, just like the code around them. Any typos will be caught at compile time, not after your app has already started.
+
+## Minimal runtime
+
+Since most of the work happens at compile time, the runtime footprint is small. The Maud runtime library, including integration with the [Rocket] and [Actix] web frameworks, is around 100 SLoC.
+
+[Rocket]: https://rocket.rs/
+[Actix]: https://actix.rs/
+
+## Simple deployment
+
+There is no need to track separate template files, since all relevant code is linked into the final executable.
