Update monkey and format instructions

Yes, the texture is extremely ugly. It's for testing :)

 - Paint the texture as desired
 - In the Image Editor window, do ~Image -> Save As~ and save the image to a lossless format (I used PNG)
 - Run the following to convert the image to ~.dds~ (which will be a larger file, but will load /drastically/ faster):
-#+BEGIN_SRC sh
-convert assets/MyTexture.png data/Materials/Textures/MyTexture.dds
-#+END_SRC
+  #+BEGIN_SRC sh
+    convert assets/MyTexture.png data/Materials/Textures/MyTexture.dds
+  #+END_SRC
 - Export the mesh. Because export materials doesn't do us any good yet, we only export the mesh to get the updated UV coordinates and material (name only)
 - Create a ~.material~ text file like below:
-#+BEGIN_SRC C
-hlms MyMaterial pbs
-{
-	roughness	0.4
-	fresnel		1.33
+  #+BEGIN_SRC C
+    hlms MyMaterial pbs
+    {
+        roughness	0.4
+        fresnel		1.33
 
-	diffuse_map		MyTexture.dds
-	// normal_map		Rocks_Normal.tga
-	// roughness_map	Rocks_Spec.tga
-	// specular_map	Rocks_Diffuse.tga
-}
-#+END_SRC
+        diffuse_map		MyTexture.dds
+        // normal_map		Rocks_Normal.tga
+        // roughness_map	Rocks_Spec.tga
+        // specular_map	Rocks_Diffuse.tga
+    }
+  #+END_SRC
 - Finally, add the material to the ~Ogre::Item~:
   #+BEGIN_SRC C++
    item->setDatablock("MyMaterial");
