 3D skinned animation
 : Skeletal animation of 3D models is similar to Spine animation but works in 3D as opposed to 2D. The 3D model is not cut into separate parts and tied to a bone like in cutout animation. Instead, the bones apply deformation to vertices in the model and you have great control over how much a bone should affect the vertices.

 Property animation
 : All numeric properties (numbers, vector3, vector4 and quaterions) and shader constants can be animated with the built in animation system, using the function `go.animate()`. The engine will automatically "tween" properties for you according to given playback modes and easing functions. You can also specify custom easing functions.

 ## Creating a model component
 
 Model components are created just like any other game object component. You can do it two ways:
 
-- Create a *Model file* by right-clicking in the *Project Explorer* and select <kbd>New ▸ Model File</kbd>.
-- Create the component embedded directly into a game object by right-clicking the game object in the *Outline* view and selecting <kbd>Add Component</kbd>. Then select *Model*.
