-### Retrieve resources from the layergroup
+## Map Tile Rendering
+
+Map tiles are used to create the graphic representation of your map in a web browser. Tiles can be requested either as pre-rendered *raster* tiles (images) or as *vector* map data to be rendered by the client (browser).
+
+- **Raster**: If a tile is requested as a raster image format, like PNG, the map will be rendered on the server, using the CartoCSS styles defined in the layers of the map. It is necessary that all the layers of a map define CartoCSS styles in order to obtain raster tiles. Raster tiles are made up of 256x256 pixels; to avoid graphic quality issues tiles should be used unscaled to represent the zoom level (Z) for which they are requested. In order to render tiles, data will be retrieved from the database (in vector format) on the server-side.
+
+- **Vector**: Tiles can also be requested as MVT (Mapbox Vector Tiles). In this case, only the geospatial vector data, without any styling, is returned. These tiles should be processed in the client-side to render the map.  In this case layers do not need to define CartoCSS, as any rendering and styling will be performed on the client side. The vector data of a tile represents real-world geometries by defining the vertices of points, lines or polygons in a tile-specific coordinate system.
+
+## Retrieve resources from the layergroup
 
 When you have a layergroup, there are several resources for retrieving layergoup details such as, accessing Mapnik tiles, getting individual layers, accessing defined Attributes, and blending and layer selection.
 
-#### Mapnik tiles
+### Raster tiles
 
-These tiles will get just the Mapnik layers. To get individual layers, see the following section.
+These raster tiles are PNG images that represent only the Mapnik layers of a map. See [individual layers](#individual-layers) for details about how to retrieve other layers.
 
 ```bash
 https://{username}.carto.com/api/v1/map/{layergroupid}/{z}/{x}/{y}.png
 ```
 
-#### Individual layers
+### Mapbox Vector Tiles (MVT)
 
-The MapConfig specification holds the layers definition in a 0-based index. Layers can be requested individually in different formats depending on the layer type.
+[Mapbox Vector Tiles (MVT)](https://www.mapbox.com/vector-tiles/specification/) are map tiles that transfer geographic vector data to the client-side. Browser performance is fast since you can pan and zoom without having to query the server.
+
+CARTO uses Web Graphics Library (WebGL) to process MVT files on the browser. This is useful since WebGL is compatible with most web browsers, include support for multiple client-side mapping engines, and do not require additional information from the server; which makes it more efficient for rendering map tiles. However, you can use any implementation tool for processing MVT files.
+
+The following examples describe how to fetch MVT tiles with a cURL request.
+
+#### MVT and Windshaft
+
+CARTO uses Windshaft as the map tiler library to render multilayer maps with the Maps API. You can use Windshaft to request MVT using the same layer type that is used for requesting raster tiles (Mapnik layer). Simply change the file format `.mvt` in the URL.
+
+
+```bash
+https://{username}.cartodb.com/api/v1/map/HASH/:layer/{z}/{x}/{y}.mvt
+```
+
+The following example instantiates an anonymous map with layer options:
+
+```bash
+{
+  user_name: 'mycartodbuser',
+  sublayers: [{
+    sql: "SELECT * FROM table_name";
+    cartocss: '#layer { marker-fill: #F0F0F0; }'
+  }],
+  maps_api_template: 'https://{user}.cartodb.com' // Optional
+}
+```
+
+**Note**: If no layer type is specified, Mapnik tiles are used by default. To access MVT tiles, specify `https://{username}.cartodb.com/api/v1/map/HASH/{z}/{x}/{y}.mvt` as the `maps_api_template` variable.
+
+**Tip:** If you are using [Named Maps](https://carto.com/docs/carto-engine/maps-api/named-maps/) to instantiate a layer, indicate the MVT file format and layer in the response:
+
+```bash
+https://{username}.cartodb.com/api/v1/map/named/:templateId/:layer/{z}/{x}/{y}.mvt
+```
+
+For all layers in a Named Map, you must indicate Mapnik as the layer filter:
+
+```bash
+https://{username}.cartodb.com/api/v1/map/named/:templateId/mapnik/{z}/{x}/{y}.mvt
+```
+
+#### Layergroup Filter for MVT Tiles
+
+To filter layers using Windshaft, use the following request where layers are numbered:
+
+```bash
+https://{username}.cartodb.com/api/v1/map/HASH/0,1,2/{z}/{x}/{y}.mvt
+```
+
+To request all layers, remove the layergroup filter parameter:
+
+```bash
+https://{username}.cartodb.com/api/v1/map/HASH/{z}/{x}/{y}.mvt
+```
+
+To filter a specific layer:
+
+```bash
+https://{username}.cartodb.com/api/v1/map/HASH/2/{z}/{x}/{y}.mvt
+```
+
+#### Example 1: MVT Tiles with Windshaft, CARTO.js, and MapboxGL
+
+1) Import the required libraries:
+
+```bash
+<script src='https://api.tiles.mapbox.com/mapbox-gl-js/v0.9.0/mapbox-gl.js'></script>
+<link href='https://api.tiles.mapbox.com/mapbox-gl-js/v0.9.0/mapbox-gl.css' rel='stylesheet' />
+<script src="http://libs.cartocdn.com/cartodb.js/v3/3.15/cartodb.core.js"></script>
+```
+
+2) Configure Map Client:
+
+```bash
+mapboxgl.accessToken = '{yourMapboxToken}';
+```
+
+3) Create Map Object (Mapbox):
+
+```bash
+var map = new mapboxgl.Map({
+container: 'map',
+zoom: 1,
+minZoom: 0,
+maxZoom: 18,
+center: [30, 0]
+});
+```
+
+4) Define Layer Options (CARTO):
+
+```bash
+var layerOptions = {
+user_name: "{username}",
+sublayers: [{
+sql: "SELECT * FROM {table_name}",
+cartocss: "...",
+     }]
+};
+```
+
+5) Request Tiles (from CARTO) and Set to Map Object (Mapbox):
+
+**Note:** By default, [CARTO core functions](https://carto.com/docs/carto-engine/carto-js/core-api/) retrieve URLs for fully rendered tiles. You must replace the default format (.png) with the MVT format (.mvt).
+
+
+```bash
+cartodb.Tiles.getTiles(layerOptions, function(result, err) {
+var tiles = result.tiles.map(function(tileUrl) {
+return tileUrl
+.replace('{s}', 'a')
+.replace(/\.png/, '.mvt');
+});
+map.setStyle(simpleStyle(tiles));
+});
+```
+
+#### Example 2: MVT Libraries with Windshaft and MapboxGL
+
+When you are not including CARTO.js to implement MVT tiles, you must use the `map.setStyle` parameter to specify vector map rendering.
+
+1) Import the required libraries:
+
+```bash
+<script src='https://api.tiles.mapbox.com/mapbox-gl-js/v0.9.0/mapbox-gl.js'></script>
+<link href='https://api.tiles.mapbox.com/mapbox-gl-js/v0.9.0/mapbox-gl.css' rel='stylesheet'/>
+```
+
+2) Configure Map Client:
+
+```bash
+mapboxgl.accessToken = '{yourMapboxToken}';
+```
+
+3) Create Map Object (Mapbox):
+
+```bash
+var map = new mapboxgl.Map({
+container: 'map',
+zoom: 1,
+minZoom: 0,
+maxZoom: 18,
+center: [30, 0]
+});
+```
+
+4) Set the Style
+
+```bash
+map.setStyle({
+    "version": 7,
+    "glyphs": "...",
+    "constants": {...},
+    "sources": {
+      "cartodb": {
+        "type": "vector",
+        "tiles": [ "http://{username}.cartodb.com/api/v1/map/named/templateId/mapnik/{z}/{x}/{y}.mvt"
+        ],
+        "maxzoom": 18
+      }
+    },
+    "layers": [{...}]
+});
+```

 ## Remove
 
 Anonymous Maps cannot be removed by an API call. They will expire after about five minutes, or sometimes longer. If an Anonymous Map expires and tiles are requested from it, an error will be raised. This could happen if a user leaves a map open and after time, returns to the map and attempts to interact with it in a way that requires new tiles (e.g. zoom). The client will need to go through the steps of creating the map again to fix the problem.
