 # Component Model design and specification
 
-This repository is where the component model is being standardized. For a more user-focused explanation, take a look at the **[Component Model Documentation]**.

 This repository contains the high-level [goals], [use cases], [design choices]
-and [FAQ] of the component model as well as a more-detailed, low-level
-[AST explainer], [async explainer], [IDL], [binary format] and [ABI] covering
-the initial Minimum Viable Product (MVP) release.

+and [Canonical ABI].
 
 In the future, this repository will additionally contain a [formal spec],
 reference interpreter and test suite.
 
 ## Milestones
 
 The Component Model is currently being incrementally developed and stabilized
-as part of [WASI Preview 2]. The subsequent "Preview 3" milestone will be
-primarily concerned with the addition of [async support].
