            <p class="light margin15"><a href="http://leaflet.cloudmade.com/" target="_blank">Leaflet</a> is a modern, lightweight open-source JavaScript library for mobile-friendly interactive maps. It is developed by <a href="http://cloudmade.com/" target="_blank">CloudMade</a>. It still has all the features most developers ever need for online maps, while providing a fast, pleasant user experience.</p>
            <p class="light margin15">The code is available on <a href="https://github.com/vizzuality/cartodb-leaflet" target="_blank">Github</a>. If you have any question there is a complete <a href="#documentation">documentation</a> or you can ask in the <a target="_blank" href="https://groups.google.com/forum/#!forum/cartodb">CartoDB mailing list</a>.</p>

          <h5 class="margin30">Usage notes</h5>
          <p class="margin15 light">If you want to get a feature clicked || hover data (via the <i>interactivity</i> parameter), the columns must be in a string separated by commas. If you don't want to write the name of the table several times, you can use {{table_name}} in the <i>query</i> or <i>tile_style</i> parameters. We strongly recommend the use of the files available in this repository. These are tested, and if you decide use updated ones, the library could not work.</p>

          <h5 class="margin30">Example</h5>

          <p class="margin15 light">First of all add the necessary script and css files:</p>

          <pre class="margin10" data-language="html">
&#60;link rel="stylesheet" href="http://cdn.leafletjs.com/leaflet-0.3.1/leaflet.css" /&#62;
&#60;!--[if IE]&#62; &#60;link rel="stylesheet" href="http://cdn.leafletjs.com/leaflet-0.3.1/leaflet.ie.css" /&#62; &#60;![endif]--&#62;
&#60;link href="css/cartodb-leaflet.css" rel="stylesheet" type="text/css"&#62;
&#60;script src="http://cdn.leafletjs.com/leaflet-0.3.1/leaflet.js"&#62;&#60;/script&#62;
&#60;script type="text/javascript" src="js/wax.leaf.min-7.0.0dev1-touched.js"&#62;&#60;/script&#62;
&#60;script type="text/javascript" src="dist/cartodb-leaflet-min.js"&#62;&#60;/script&#62;
          </pre>


          <p class="margin15 light">When the document is loaded, start creating the map:</p>

          <pre data-language="javascript">
var map = new L.Map('map');
var cloudmadeUrl = 'http://{s}.tile.cloudmade.com/BC9A493B41014CAABB98F0471D759707/997/256/{z}/{x}/{y}.png',
  cloudmadeAttrib = 'Map data &copy; 2011 OpenStreetMap contributors, Imagery &copy; 2011 CloudMade',
  cloudmade = new L.TileLayer(cloudmadeUrl, {maxZoom: 18, attribution: cloudmadeAttrib});
map.addLayer(cloudmade);
          </pre>
            
          <p class="margin20 light">Then create the CartoDB layer:</p>

          <pre class="margin10" data-language="javascript">
var cartodb_leaflet = new L.CartoDBLayer({
  map: map,
  user_name:'example',
  table_name: 'earthquakes',
  query: "SELECT * FROM {{table_name}}",
  tile_style: "#{{table_name}}{marker-fill:red}",
  interactivity: "cartodb_id, magnitude",
  featureClick: function(ev, latlng, pos, data) {alert(data)},
  featureOut: function() {},
  featureOver: function(ev, latlng, pos, data) {},
  auto_bound: true
});
          </pre>

          <p class="margin20 light">And finally add it to the map:</p>

          <p class="margin15 light">If you want to use the cartodb custom popup, you need to add the script in the html:</p>
          <pre class="margin10" data-language="html">
&#60;script type="text/javascript" src="dist/cartodb-popup-min.js"&#62;&#60;/script&#62;
          </pre>

          <p class="light margin15">Create the CartoDB popup:</p>
          <pre data-language="javascript">
var popup = new L.CartoDBPopup();
          </pre>

          <p class="light margin15">And then use as you want:</p>
          <pre data-language="javascript">
...
featureClick: function(ev,latlng,pos,data) {
  // Set popup content
  // You can pass an Object, an Array or a String
  popup.setContent(data);

  // Set latlng
  popup.setLatLng(latlng);

  // Show it!
  map.openPopup(popup);
},
...
