 ## Use Case
 
-Why is this pattern is important?
+I wish to provide the user with something to look at before they choose to start interacting with the object, and/or while they wait for it to load/buffer.
 
 ## Implementation notes
 
+For this value, it's particularly important to note the latitude given conforming clients. The spec only says that clients _may_ render the `placeholderCanvas` property, not _must_.
+
+Note also the differences between this property and the `accompanyingCanvas` property. This property provides content to render before the main content is rendered 
+
 How does one implement the pattern?

 ## Use Case
 
-Provide the user with something to look at before they choose to start interacting with the main content, and/or while they wait for it to load/buffer, and/or while interacting with the main content.
+You have a long video to present to site visitors. As each visitor's connection reliability and bandwidth are unknown and unpredictable, you want to show them a more lightweight resource (which will load more quickly) until the video has finished loading or has sufficiently buffered. 
 
 ## Implementation notes
 
-For this property, it's particularly important to note the latitude given conforming clients. The IIIF Presentation API 3.0 only says that clients _may_ render the `placeholderCanvas` property, not _must_.
+Across a Manifest and its properties, you may use more than one `placeholderCanvas`, allowing you to have an authentic `placeholderCanvas` for each appropriate resource (Collection, Manifest, Canvas, and Range). 
 
-Note also the differences between this property and the `accompanyingCanvas` property. Only this property is used to load content before the main content is loaded. Either `placeholderCanvas` or `accompanyingCanvas` can be used for content while the user is interacting with the main content, with slightly different semantics. `placeholderCanvas` and `accompanyingCanvas` are each appropriate for describing an image to be shown while the main audio content is playing. `accompanyingCanvas` is more appropriate to use for audio to play while a user is interacting with a visual object.
+Always keep in mind the wide latitude given conforming clients: It is up to the client whether and in what sort of UI to display content you place in a `placeholderCanvas` property. Don't use this property for content that must be displayed.

 ## Restrictions

+Each instance of `placeholderCanvas` may only contain one Canvas, and as such may specifically not contain an additional `placeholderCanvas` or an `accopanyingCanvas`.
 
 ## Example

+Across a Manifest and its resources, you may use more than one `placeholderCanvas`, allowing you to have an authentic `placeholderCanvas` for each appropriate resource (Collection, Manifest, Canvas, and Range).
+
+The target of the Annotation of a `placeholderCanvas` should have as its value the id of the `placeholderCanvas`, not the id of the resource that has the `placeholderCanvas`.
 
 Always keep in mind the wide latitude given conforming clients: It is up to the client whether and in what sort of UI to display content you place in a `placeholderCanvas` property. Do not use this property for content that must be displayed. On the other hand, placing content in a `placeholderCanvas` does communicate to a conforming client that the content, if displayed, should be displayed before the resource to which it is attached.
