+
+Is as stylesheet renderer for javascript, It's an evolution of the Mapnik renderer from Mapbox.
+Please, see original [Mapbox repo](http://github.com/mapbox/carto) for more information and credits
+
+## Quick Start
+
+```javascript
+// shader is a CartoCSS object
+
+var cartocss = [
+    '#layer {',
+    ' marker-width: [property]',
+    ' marker-fill: red',
+    '}'
+].join('')
+var shader = new carto.RendererJS().render(cartocss);
+var layers = shader.getLayers()
+for (var i = 0; i < layers.length; ++i) {
+    var layer = layers[i];
+    console.log("layer name: ", layer.fullName())
+    console.log("- frames: ", layer.frames())
+    console.log("- attachment: ", layer.attachment())
+
+    var layerShader = layer.getStyle({ property: 1 }, { zoom: 10 })
+    console.log(layerShader['marker-width']) // 1
+    console.log(layerShader['marker-fill']) // #FF0000
+}
+
+```
+
+# API
+
+## RendererJS
+
+### render(cartocss)
+
+## CartoCSS
+
+compiled cartocss object
+
+### getLayers
+
+return the layers, an array of ``CartoCSS.Layer`` object
+
+### getDefault
+
+return the default layer (``CartoCSS.Layer``), usually the Map layer
+
+
+### findLayer(where)
+
+find a layer using where object.
+
+```
+shader.findLayer({ name: 'test' })
+```
+
+## CartoCSS.Layer
+
+### getStyle(props, context)
+
+return the evaluated style:
+    - props: object containing properties needed to render the style. If the cartocss style uses
+      some variables they should be passed in this object
+    - context: rendering context variables like ``zoom`` or animation ``frame``
+
+
+

-Is a stylesheet renderer for Mapnik. It's an evolution of the
-[Cascadenik](https://github.com/mapnik/Cascadenik) idea and language,
-with an emphasis on speed and flexibility.
 
 ## Reference Documentation
 
 * [mapbox.com/carto](http://mapbox.com/carto/)
 
-## MML
-_incompatibility_
 
-* MML files are assumed to be JSON, not XML. The files are near-identical
-  to the XML files accepted by Cascadenik, just translated into JSON.
-* CartoCSS will not embed files or download URLs for you. Stylesheets should
-  be embedded directly into your MML JSON and any datasources should be
-  paths (relative or absolute) that would be acceptable in Mapnik XML.
-  The [millstone project](https://github.com/mapbox/millstone) aims to fill this need.
-
-CartoCSS MML:

-
-## Attachments and Instances
-_new_
-
-In CSS, a certain object can only have one instance of a property. A `<div>` has a specific border width and color, rules that match better than others (#id instead of .class) override previous definitions. `CartoCSS` acts the same way normally for the sake of familiarity and organization, but Mapnik itself is more powerful.
-
-Layers in Mapnik can have multiple [borders](http://trac.mapnik.org/wiki/LineSymbolizer) and multiple copies of other attributes. This ability is useful in drawing line outlines, like in the case of road borders or 'glow' effects around coasts. `CartoCSS` makes this accessible by allowing attachments to styles:
-
-    #world {
-      line-color: #fff;
-      line-width: 3;
-      }
-
-      #world::outline {
-        line-color: #000;
-        line-width: 6;
-        }
-
-Attachments are optional: if you don't define them, CartoCSS does overriding of styles just like Cascadenik.
-
-This brings us to another _incompatibility_: `line-inline` and `line-outline` have been removed from the language, because attachments are capable of the same trick.
-
-While attachments allow creating implicit "layers" with the same data, using **instances** allows you to create multiple symbolizers in the same style/layer:
-
-    #roads {
-      casing/line-width: 6;
-      casing/line-color: #333;
-      line-width: 4;
-      line-color: #666;
-      }
-
-This makes Mapnik first draw the line of color #333 with a width of 6, and then immediately afterwards, it draws the same line again with width 4 and color #666. Contrast that to attachments: Mapnik would first draw all casings before proceeding to the actual lines.
-
-## text-name
-_incompatibility_
-
-Instead of the name attribute of the [TextSymbolizer](http://trac.mapnik.org/wiki/TextSymbolizer) and [ShieldSymbolizer](http://trac.mapnik.org/wiki/ShieldSymbolizer) being a part of the selector, it is a property of a rule. Thus the evaluation is less complex and one can use expressions in names.

-## Mapnik
-_new_
-
-CartoCSS is only compatible with Mapnik >= 2.x.x.
-
-## Rasters and Buildings
-_new_
-
-Rasters are supported in CartoCSS - it knows how to download `.vrt`, `.tiff`, and soon other raster formats, and the properties of the [RasterSymbolizer](http://trac.mapnik.org/wiki/RasterSymbolizer) are exposed in the language.
-
-The [BuildingSymbolizer](http://trac.mapnik.org/wiki/BuildingSymbolizer) is also supported in `CartoCSS`. The code stores symbolizer types and properties in a JSON file (in `tree/reference.json`), so new Mapnik features can be quickly implemented here.
-
-## Variables & Expressions
-_new_
-
-CartoCSS inherits from its basis in [less.js](http://lesscss.org/) some new features in CSS. One can define variables in stylesheets, and use expressions to modify them.
-
-    @mybackground: #2B4D2D;
-    
-    Map {
-      background-color: @mybackground
-    }
-    
-    #world {
-      polygon-fill: @mybackground + #222;
-      line-color: darken(@mybackground, 10%);
-    }
-
-## Nested Styles
-_new_
-
-CartoCSS also inherits nesting of rules from less.js.
-
-    /* Applies to all layers with .land class */
-    .land {
-      line-color: #ccc;
-      line-width: 0.5;
-      polygon-fill: #eee;
-      /* Applies to #lakes.land */
-      #lakes {
-        polygon-fill: #000;
-      }
-    }
-
-This can be a convenient way to group style changes by zoom level:
-
-    [zoom > 1] {
-      /* Applies to all layers at zoom > 1 */
-      polygon-gamma: 0.3;
-      #world {
-        polygon-fill: #323;
-      }
-      #lakes {
-        polygon-fill: #144;
-      }
-    }
-
-## FontSets
-
-_new_
-
-By defining multiple fonts in a `text-face-name` definition, you create [FontSets](http://trac.mapnik.org/wiki/FontSet) in `CartoCSS`. These are useful for supporting multiple character sets and fallback fonts for distributed styles.
-
-<table>
-  <tr>
-    <th>carto</th><th>XML</th>
-    </tr>
-    <tr>
-    <td valign='top'>
-
-    <pre>#world {
-  text-name: "[NAME]";
-  text-size: 11;
-  text-face-name: "Georgia Regular", "Arial Italic";
-}</pre>
-
-</td>
-<td valign='top'>
-<pre>&lt;FontSet name=&quot;fontset-0&quot;&gt;
-  &lt;Font face-name=&quot;Georgia Regular&quot;/&gt;
-  &lt;Font face-name=&quot;Arial Italic&quot;/&gt;
-&lt;/FontSet&gt;
-&lt;Style name=&quot;world-text&quot;&gt;
-  &lt;Rule&gt;
-    &lt;TextSymbolizer fontset-name=&quot;fontset-0&quot;
-      size=&quot;11&quot;
-      name=&quot;[NAME]&quot;/&gt;
-  &lt;/Rule&gt;
-&lt;/Style&gt;</pre>
-</td>
-<tr>
-</table>
-
-## Filters
-
-CartoCSS supports a variety of filter styles:
-
-Numeric comparisons:
-
-```
-#world[population > 100]
-#world[population < 100]
-#world[population >= 100]
-#world[population <= 100]
-```
-
-General comparisons:
-
-```
-#world[population = 100]
-#world[population != 100]
-```
-
-
-String comparisons:
-
-```
-/* a regular expression over name */
-#world[name =~ "A.*"]
-```
-
-## Developers
-
-#### Installation
-
-If you're using [TileMill](http://mapbox.com/tilemill/), you're already
-using CartoCSS and don't need to do a thing.
-
-If you're a developer-type and want to use the `carto` binary with
-`node.js` (and you have [npm](http://npmjs.org/) installed),
-
-    npm install -g carto
-
-#### From the binary
-
-Install `millstone` to enable support for localizing external resources (URLs and local files) referenced in your mml file.
-
-    npm install millstone
-    carto map_file.json
-
-#### From code
-
-Currently CartoCSS is designed to be invoked from [node.js](http://nodejs.org/).
-The `Renderer` interface is the main API for developers, and it takes an MML file as a string as input.
-
-    // defined variables:
-    // - input (the name or identifier of the file being parsed)
-    // - data (a string containing the MML or an object of MML)
-    var carto = require('carto');
-    
-    new carto.Renderer({
-            filename: input,
-            local_data_dir: path.dirname(input),
-        }).render(data, function(err, output) {
-            if (err) {
-                if (Array.isArray(err)) {
-                    err.forEach(function(e) {
-                        carto.writeError(e, options);
-                    });
-                } else { throw err; }
-            } else {
-                sys.puts(output);
-            }
-        });
-
-### Vim
-
-To install, download or clone this repository, then add the `vim-carto`
-directory located at `build/vim-carto` to your `~/.vim` file.

+# Carto documentation
+
+The following is a list of properties provided in CartoCSS that you can apply to map elements.
+<%= table({symbolizers:symbolizers}) %>
+
+### Values
+
+Below is a list of values and an explanation of any expression that can be applied to properties in CartCSS.
+
+### Color
+
+CartoCSS accepts a variety of syntaxes for colors - HTML-style hex values, rgb, rgba, hsl, and hsla. It also supports the predefined HTML colors names, like `yellow` and `blue`.
+
+``` css
+#line {
+line-color: #ff0;
+line-color: #ffff00;
+line-color: rgb(255, 255, 0);
+line-color: rgba(255, 255, 0, 1);
+line-color: hsl(100, 50%, 50%);
+line-color: hsla(100, 50%, 50%, 1);
+line-color: yellow;
+}
+```
+
+Especially of note is the support for hsl, which can be [easier to reason about than rgb()](http://mothereffinghsl.com/). Carto also includes several color operation functions [borrowed from less](http://lesscss.org/functions/#color-operations):
+
+``` css
+// lighten and darken colors
+lighten(#ace, 10%);
+darken(#ace, 10%);
+
+// saturate and desaturate
+saturate(#550000, 10%);
+desaturate(#00ff00, 10%);
+
+// increase or decrease the opacity of a color
+fadein(#fafafa, 10%);
+fadeout(#fefefe, 14%);
+
+// spin rotates a color around the color wheel by degrees
+spin(#ff00ff, 10);
+
+// mix generates a color in between two other colors.
+mix(#fff, #000, 50%);
+```
+
+These functions all take arguments which can be color variables, literal colors, or the results of other functions operating on colors.
+
+### Float
+
+Float is a fancy way of saying 'number'. In CartoCSS, you specify _just a number_ - unlike CSS, there are no units, but everything is specified in pixels.
+
+``` css
+#line {
+line-width: 2;
+}
+```
+
+It's also possible to do simple math with number values:
+
+``` css
+#line {
+line-width: 4 / 2; // division
+line-width: 4 + 2; // addition
+line-width: 4 - 2; // subtraction
+line-width: 4 * 2; // multiplication
+line-width: 4 % 2; // modulus
+}
+```
+
+### URI
+
+URI is a fancy way of saying URL. When an argument is a URI, you use the same kind of `url('place.png')` notation that you would with HTML. Quotes around the URL aren't required, but are highly recommended. URIs can be paths to places on your computer, or on the internet.
+
+```css
+#markers {
+marker-file: url('marker.png');
+}
+```
+
+### String
+
+A string is basically just text. In the case of CartoCSS, you're going to put it in quotes. Strings can be anything, though pay attention to the cases of `text-name` and `shield-name` - they actually will refer to features, which you refer to by putting them in brackets, as seen in the example below.
+
+```css
+#labels {
+text-name: "[MY_FIELD]";
+}
+```
+
+### Boolean
+
+Boolean means yes or no, so it accepts the values `true` or `false`.
+
+```css
+#markers {
+marker-allow-overlap:true;
+}
+```
+
+### Expressions
+
+Expressions are statements that can include fields, numbers, and other types in a really flexible way. You have run into expressions before, in the realm of 'fields', where you'd specify `"[FIELD]"`, but expressions allow you to drop the quotes and also do quick addition, division, multiplication, and concatenation from within Carto syntax.
+
+```css
+#buildings {
+building-height: [HEIGHT_FIELD] * 10;
+}
+```
+
+### Numbers
+Numbers are comma-separated lists of one or more number in a specific order. They're used in line dash arrays, in which the numbers specify intervals of line, break, and line again.
+
+```css
+#disputedboundary {
+line-dasharray: 1, 4, 2;
+}
+```
+
+### Percentages
+In Carto, the percentage symbol, `%` universally means `value/100`. It's meant to be used with ratio-related properties, like opacity rules.
+
+_You should not use percentages as widths, heights, or other properties - unlike CSS, percentages are not relative to cascaded classes or page size, they're, as stated, simply the value divided by one hundred._
+
+```css
+#world {
+// this syntax
+polygon-opacity: 50%;
+
+// is equivalent to
+polygon-opacity: 0.5;
+}
+```
+
+### Functions
+
+Functions are comma-separated lists of one or more functions. For instance, transforms use the `functions` type to allow for transforms within Carto, which are optionally chainable.
+
+```css
+#point {
+point-transform: scale(2, 2);
+}
+```
