-### `L.VectorGrid.Slicer`
+* `L.VectorGrid.Slicer` for displaying GeoJSON or TopoJSON data
+* `L.VectorGrid.Protobuf` for displaying vector tiles from an online tile server
 
-Slices some GeoJSON data into tiles, via `geojson-vt`.
+You can find the API documentation, and the explanation about the styling, at:
 
-Instantiate through the factory method:
+http://leaflet.github.io/Leaflet.VectorGrid/vectorgrid-api-docs.html
 
-```js
-var layer = L.vectorGrid.slicer(geojson, options);
-```
-
-Any options to `geojson-vt` can be passed in `options`.
-
-Styling-wise, this will create an internal vector tile layer named `sliced`. This can be overridden with the `vectorTileLayerName` option.
-
-The slicer also accepts [TopoJSON](https://github.com/mbostock/topojson) transparently:
-```js
-var layer = L.vectorGrid.slicer(topojson, options);
-```
-
-The TopoJSON format [implicitly groups features into "objects"](https://github.com/mbostock/topojson-specification/blob/master/README.md#215-objects). These will be transformed into vector tile layer names when styling (the `vectorTileLayerName` option is ignored when using TopoJSON).
-
-### `L.VectorGrid.Protobuf`
-
-Reads vector tiles in Protobuf (`.pbf`) format from the network.
-
-Instantiate through the factory method:
-
-```js
-var layer = L.vectorGrid.protobuf(url, options);
-```
-
-`url` is a URL template for `.pbf` vector tiles, e.g.:
-
-```js
-var url = 'https://{s}.tiles.mapbox.com/v4/mapbox.mapbox-streets-v6/{z}/{x}/{y}.vector.pbf';
-var layer = L.vectorGrid.protobuf(url, options);
-```
-
-### Styling
-
-Vector tiles have a concept of "layer" different from the Leaflet concept of "layer".
-
-In Leaflet, a "layer" is something that can be atomically added or removed from the map. In vector tiles, a "layer" is a named set of features (points, lines or polygons) which share a common theme.
-
-A vector tile layer¹ can have several layers². In the `mapbox-streets-v6` vector tiles layer¹ above, there are named layers² like `admin`, `water` or `roads`.
-
-* ¹ In leaflet
-* ² Groups of themed features
-
-Styling is done via per-layer² sets of `L.Path` options in the `vectorTileLayerStyles` layer¹ option:
-
-```js
-
-var vectorTileOptions = {
-	vectorTileLayerStyles: {
-
-		water: {
-			weight: 0,
-			fillColor: '#9bc2c4',
-			fillOpacity: 1,
-			fill: true
-		},
-
-		admin: function(properties, zoom) {
-			var level = properties.admin_level;
-			var weight = 1;
-			if (level == 2) {weight = 4;}
-			return {
-				weight: weight,
-				color: '#cf52d3',
-				dashArray: '2, 6',
-				fillOpacity: 0
-			}
-		},
-
-		road: []
-	}
-};
-
-Polylines and polygons can be styled exactly like normal Leaflet overlays, points can be styled like CircleMarkers.
-
-
-var pbfLayer = L.vectorGrid.protobuf(url, vectorTileOptions).addTo(map);
-```
-
-A layer² style can be either:
-* A set of `L.Path` options
-* An array of sets of `L.Path` options
-* A function that returns a set of `L.Path` options
-* A function that returns an array of sets of `L.Path` options
-
-Layers² with no style specified will use the default `L.Path` options.
-
-#### Updating styles
-
-In some cases it can be desirable to change the style of a feature on screen, for example for highlighting when a feature is clicked.
-
-To do this, VectorGrid needs to know how to identify a feature. This is done through the `getFeatureId` option, which should be set to a function
-that returns an id given a feature as argument. For example:
-
-```js
-var vectorGrid = L.vectorGrid.slicer(url, {
-	...
-	getFeatureId: function(f) {
-		return f.properties.osm_id;
-	}
-}
-```
-
-Note that features with the same id will be treated as one when changing style, this happens normally when for example a polygon spans more than one tile.
-
-To update the style of a feature, use `setFeatureStyle`:
-
-```js
-vectorGrid.setFeatureStyle(id, style);
-```
-
-The styling follows the same rules as described above, it accepts a single style, an array, or a function that returns styling.
-
-To revert the style to the layer's default, use the `resetFeatureStyle` method:
-
-```js
-vectorGrid.resetFeatureStyle(id);
-```
-
-### Interaction
-
-You can enable interacting (click, mouseover, etc.) with layer features if you pass the option `interactive: true`; you can then add listeners to the VectorGrid layer. When
-an event fires, it will include the `layer` property, containing information about the feature.
-
-### SVG vs `<canvas>`
-
-Leaflet.VectorGrid is able to render vector tiles with both SVG and `<canvas>`, in the same way that vanilla Leaflet can use SVG and `<canvas>` to draw lines and polygons.
-
-To switch between the two, use the `rendererFactory` option for any `L.VectorGrid` layer, e.g.:
-
-```js
-var sliced = L.vectorGrid.slicer(geojson, {
-	rendererFactory: L.svg.tile,
-	attribution: 'Something',
-	vectorTileLayerStyles: { ... }
-});
-
-var pbf = L.vectorGrid.protobuf(url, {
-	rendererFactory: L.canvas.tile,
-	attribution: 'Something',
-	vectorTileLayerStyles: { ... }
-});
-```
-
-Internally, Leaflet.VectorGrid uses two classes named `L.SVG.Tile` and `L.Canvas.Tile`, with factory methods `L.svg.tile` and `L.canvas.tile` - a `L.VectorGrid` needs to be passed one of those factory methods.

+ * 🍂class VectorGrid.Protobuf
+ * 🍂extends VectorGrid
+ *
+ * A `VectorGrid` for vector tiles fetched from the internet.
+ * Tiles are supposed to be protobufs (AKA "protobuffer" or "Protocol Buffers"),
+ * containing data which complies with the
+ * [MapBox Vector Tile Specification](https://github.com/mapbox/vector-tile-spec/tree/master/2.1).
+ *
+ * This is the format used by:
+ * - Mapbox Vector Tiles
+ * - Mapzen Vector Tiles
+ * - ESRI Vector Tiles
+ * - [OpenMapTiles hosted Vector Tiles](https://openmaptiles.com/hosting/)
+ *
+ * 🍂example
+ *
+ * You must initialize a `VectorGrid.Protobuf` with a URL template, just like in
+ * `L.TileLayer`s. The difference is that the template must point to vector tiles
+ * (usually `.pbf` or `.mvt`) instead of raster (`.png` or `.jpg`) tiles, and that
+ * you should define the styling for all the features.
+ *
+ * <br><br>
+ *
+ * For OpenMapTiles, with a key from [https://openmaptiles.org/docs/host/use-cdn/](https://openmaptiles.org/docs/host/use-cdn/),
+ * initialization looks like this:
+ *
+ * ```
+ * L.vectorGrid.protobuf("https://free-{s}.tilehosting.com/data/v3/{z}/{x}/{y}.pbf.pict?key={key}", {
+ * 	vectorTileLayerStyles: { ... },
+ * 	subdomains: "0123",
+ * 	key: 'abcdefghi01234567890',
+ * 	maxNativeZoom: 14
+ * }).addTo(map);
+ * ```
+ *
+ * And for Mapbox vector tiles, it looks like this:
+ *
+ * ```
+ * L.vectorGrid.protobuf("https://{s}.tiles.mapbox.com/v4/mapbox.mapbox-streets-v6/{z}/{x}/{y}.vector.pbf?access_token={token}", {
+ * 	vectorTileLayerStyles: { ... },
