+If you add a ContentProcessor, you will be able to map the output of the supplied importer to custom classes tailored specifically for your game.
 
 ## Basic usecase
 ```csharp
 using (var stream = File.OpenRead(filename))
 {
-  var map = Map.FromStream(stream, ts => File.OpenRead(Path.Combine(Path.GetDirectoryName(filename), ts.source)));
+    var map = Map.FromStream(stream, ts => File.OpenRead(Path.Combine(Path.GetDirectoryName(filename), ts.Source)));
 
-  foreach (var layer in map.Layers.OfType<TileLayer>())
-  {
-    for (int y = 0, i = 0; y < layer.Height; y++)
-      for (int x = 0; x < layer.Width; x++, i++)
-      {
-        var gid = layer.data[i];
-        if (gid == 0)
-            continue;
+    foreach (var layer in map.Layers.OfType<TileLayer>())
+    {
+        for (int y = 0, i = 0; y < layer.Height; y++)
+            for (int x = 0; x < layer.Width; x++, i++)
+            {
+                var gid = layer.data[i];
+                if (gid == 0)
+                    continue;
 
-        var tileset = map.Tilesets.Single(ts => gid >= ts.firstgid && ts.firstgid + ts.TileCount > gid);
-        var tile = tileset[gid];
+                var tileset = map.Tilesets.Single(ts => gid >= ts.FirstGid && ts.FirstGid + ts.TileCount > gid);
+                var tile = tileset[gid];
 
-        // Do stuff with the tile.
-      }
-  }
+                // Do stuff with the tile.
+            }
