+## What is ReactiveSwift in a nutshell?
 __ReactiveSwift__ offers composable, declarative and flexible primitives that are built around the grand concept of ___streams of values over time___.
 
 These primitives can be used to uniformly represent common Cocoa and generic programming patterns that are fundamentally an act of observation, e.g. delegate pattern, callback closures, notifications, control actions, responder chain events, [futures/promises](https://en.wikipedia.org/wiki/Futures_and_promises) and [key-value observing](https://developer.apple.com/library/mac/documentation/Cocoa/Conceptual/KeyValueObserving/KeyValueObserving.html) (KVO).

 it’s easy to declaratively compose them together, with less spaghetti
 code and state to bridge the gap.
 
-## Getting Started
-
-1. **[Core Reactive Primitives][]**
-
-   An overview of the semantics and example use cases of the ReactiveSwift primitives, including [`Signal`][], [`SignalProducer`][], [`Property`][] and [`Action`][].
-
-1. **[Basic Operators][]**
-
-   An overview of the operators provided to compose and transform streams of values.
-   
-1. **[ReactiveCocoa][ReactiveCocoa]**
-
-   Building on top of ReactiveSwift, **ReactiveCocoa** extends Cocoa platform frameworks with reactive bindings and extensions.

-1. **[How does ReactiveSwift relate to RxSwift?][]**
-
-   An overview of how ReactiveSwift differs from RxSwift for Swift idiomaticity.
-   
-## Examples
-
-1. **Interactive Form UI**
-
-     ReactiveSwift includes a [_UI Examples_ playground][], which demonstrates:
-     * how to build an interactive form UI with bindings, properties and `Action`s, with a live view in action.
-     * how to use reactive primitives to implement the Model-View-ViewModel architectural pattern, with the View Model being the source of truth for the View.

-## Advanced Topics
-
-1. **[ReactiveCocoa][]**
-   
-   Bindings and reactive extensions for Cocoa and Cocoa Touch frameworks are offered separately as ReactiveCocoa.

 ### Plan of Record
 #### ABI stability release
-ReactiveSwift is expected to declare library ABI stability when Swift rolls out resilence support. Until then, ReactiveSwift would incrementally adopt new language features that help move towards to goal.
+ReactiveSwift has no plan to declare ABI and module stability at the moment. It will continue to be offered as a source only dependency for the foreseeable future.
