 We currently recommend creating the map using [Tiled](https://www.mapeditor.org/). For that we use `WorldMapByTiled` in `BonfireWidget` in the `map` parameter:
 
 ```dart
-WorldMapByTiled(TiledReader.asset('tile/map.json'), forceTileSize: Size(32,32))
+WorldMapByTiled(WorldMapReader.fromAsset('tile/map.json'))
 ```
 
 The first parameter (`tile/map.json`) is the path of the `.json` file exported by Tiled.
 
 > IMPORTANT: Bonfire only supports .json files.
 
-The second parameter (`Size(32,32)`) is optional and determines the size of each Tile on the map (squares). If not set it takes the default size defined by your TileSet.
-
 You can load a map from url. Just pass the url in path. Example:
 
 ```dart
 WorldMapByTiled(
-    TiledReader.network( Uri.parse('https://raw.githubusercontent.com/RafaelBarbosatec/rafaelbarbosatec.github.io/master/tiled/my_map.json')),
