 Read maps from the [Tiled Map Editor](http://www.mapeditor.org/) into rust for use in video games. It is game engine agnostic and pretty barebones at the moment. Documentation is available [on rust-ci](http://rust-ci.org/mattyhall/rs-tiled/doc/tiled/).
 
 
+### Example
+
+```rust
+extern crate serialize;
+extern crate xml;
+extern crate tiled;
+
+use std::io::File;
+use std::io::BufferedReader;
+use xml::reader::EventReader;
+use tiled::parse;
+
+fn main() {
+    let file = File::open(&Path::new("assets/tiled_base64_zlib.tmx")).unwrap();
+    println!("Opened file");
+    let reader = BufferedReader::new(file);
+    let mut parser = EventReader::new(reader);
+    let map = parse(&mut parser).unwrap();
+    println!("{}", map);
+    println!("{}", map.get_tileset_by_gid(22));

   * Image layers
   * A nice API. At the moment you can access attributes and properties, find tilesets by GID and loop through the tiles. This leaves a user of the library with a bit to do.
