 There are two distinct items in the Primum Machina: the Entity, and the Component. Components give qualities to Entities. An Entity is any real, tangible thing in the universe, and so every entity has a position. Components do not necessarily have a position; they can be things like the image that draws where the entity is located, and colliders that allow the entity to respond with the world.
 
 ### Components
-The most "bare metal" are the components. These are essentially hooks into the engine that tell it how to do particular things. For example, to render a sprite, Javascript does no rendering, but rather tells the engine to create an image and render it in a particular spot.
+The most "bare metal" are the components. These are essentially hooks into the engine that tell it how to do particular things. For example, to render a sprite, Javascript does no rendering, but rather tells the engine to create an image and render it in a particular spot. Javascript does the accounting to make or destroy the sprite as needed - but besides that initial startup, no scripting is done.
