-Objloader is a simple Wavefront .obj and .mtl loader
+Objloader is a simple Wavefront .obj and .mtl loader.
 
 Installation 
 ------------
 Build the project and reference the .dll or reference the project directly as usual.
 
 Loading a model
 ---------------
-Either create the loader with the standard material stream provider, this will open the file read-only from the working directory.
-
-	var objLoaderFactory = new ObjLoaderFactory();
-	var objLoader = objLoaderFactory.Create();
 
+Either create the loader with the standard material stream provider, this will open the file read-only from the working directory.
+```cs
+var objLoaderFactory = new ObjLoaderFactory();
+var objLoader = objLoaderFactory.Create();
+```
 
 Or provide your own:
-
-    //With the signature Func<string, Stream>
-    var objLoaderFactory = new ObjLoaderFactory();
-    var objLoader = objLoaderFactory.Create(materialFileName => File.Open(materialFileName);
+```cs
+//With the signature Func<string, Stream>
+var objLoaderFactory = new ObjLoaderFactory();
+var objLoader = objLoaderFactory.Create(materialFileName => File.Open(materialFileName);
+```
 
 Then it is just a matter of invoking the loader with a stream containing the model. 
-
-    var fileStream = new FileStream("model.obj");
-    var result = objLoader.Load(fileStream);
+```cs
+var fileStream = new FileStream("model.obj");
+var result = objLoader.Load(fileStream);
+```
 
 The result object contains the loaded model in this form:
-
-    public class LoadResult  
-    {
-        public IList<Vertex> Vertices { get; set; }
-        public IList<Texture> Textures { get; set; }
-        public IList<Normal> Normals { get; set; }
-        public IList<Group> Groups { get; set; }
-        public IList<Material> Materials { get; set; }
-    }
+```cs	
+public class LoadResult  
+{
+    public IList<Vertex> Vertices { get; set; }
+    public IList<Texture> Textures { get; set; }
+    public IList<Normal> Normals { get; set; }
+    public IList<Group> Groups { get; set; }
+    public IList<Material> Materials { get; set; }
+}
+```
