+## Features
+
+Lightweight Obserservable is a simple implementation of an observable sequence that you can subscribe to. The framework is designed to be minimal meanwhile convenient. The entire code is only ~80 lines (excluding comments). With Lightweight Observable you can easily set up UI-Bindings in an MVVM application, handle asynchronous network calls and a lot more.
+
+**Credits:** The code was heavily influenced by [roberthein/observable](https://github.com/roberthein/Observable). However I needed something that was syntactically closer to [RxSwift](https://github.com/ReactiveX/RxSwift), which is why I came up with this code, and for reusability reasons afterwards moved it into a CocoaPod.
+
+### Example
+To run the example project, clone the repo, and open the workspace from the Example directory.
+
+### Integration
+##### CocoaPods
+LightweightObservable can be added to your project using [CocoaPods](https://cocoapods.org/) by adding the following line to your Podfile:
+```
+pod 'LightweightObservable', '~> 1.0'
+```
+
+##### Carthage
+To integrate LightweightObservable into your Xcode project using [Carthage](https://github.com/Carthage/Carthage), specify it in your Cartfile:
+```
+github "fxm90/LightweightObservable" ~> 1.0
+```
+Run carthage update to build the framework and drag the built `LightweightObservable.framework` into your Xcode project.
+
+### How to use
+The framework provides two classes `Observable` and `Variable`:
+ - `Observable`: Contains an immutable value, you only can subscribe to. This is useful in order to avoid side-effects on an internal API. 
+ - `Variable`: Subclass of `Observable`, where you can modify the value as well.
+
+Feel free to check out the example application for a better understanding of this approach.
+
+#### – Create a variable
+```swift
+let formattedTimeSubject = Variable("")
+
+// ...
+
+formattedTimeSubject.value = "4:20 PM"
+```
+
+#### – Create an observable
+Initializing an observable directly is not possible, as this would lead to a sequence that will never change. Instead, use the computed property `asObservable` from `Variable` to cast the instance to an observable.
+```swift
+var formattedTime: Observable<String> {
+    return formattedTimeSubject.asObservable
+}
+```
+
+#### – Subscribe to changes
+Every subscriber gets initialized with the current value and updated on all further changes to the observable value.
+
+```swift
+formattedTime.subscribe { [weak self] newFormattedTime, oldFormattedTime in
+    self?.timeLabel.text = newFormattedTime
+}
+```
+
+Please notice that the old value (`oldFormattedTime`) is an optional of the underlying type, as we don't have this value on the initial call to the subscriber.
+
+**Important:** To avoid retain cycles and/or crashes, **always** use `[weak self]` when self is needed by an observer.
+
+#### – Memory Management (`Disposable` / `DisposeBag`)
+
+When you subscribe to an `Observable` the method returns a `Disposable`, which is basically a reference to the new subscription.
+
+We need to maintain it, in order to properly control the lifecycle of that subscription.
+
+Let me explain you why in a little example:
+
+> Imagine having a MVVM application using a service layer for network calls. A service is used as a singleton across the entire app.
+> 
+> The view-model has a reference to a service and subscribes to an observable property. The subscription-closure is now saved inside the observable property on the service.
+> 
+> If the view-model gets deallocated (e.g. due to a dismissed view-controller), without noticing the observable property somehow, the subscription-closure would continue to be alive. 
+> 
+> As a workaround, we store the returned disposable from the subscription on the view-model. On deallocation of the disposable, it automatically informs the observable property to remove the referenced subscription closure.
+
+In case you only use a single subscriber you can store the returned `Disposable` to a variable:
+```swift
+let disposable = formattedTime.subscribe { [weak self] newFormattedTime, oldFormattedTime in
+	// ...
+}
+```
+
+In case you're having multiple observers, you can store all returned `Disposable` in an array of `Disposable`. (To match the syntax from [RxSwift](https://github.com/ReactiveX/RxSwift), this pod contains a typealias called `DisposeBag`, which is an array of `Disposable`).
+```swift
+var disposeBag = DisposeBag()
+
+formattedTime.subscribe { [weak self] newFormattedTime, oldFormattedTime in
+    // ...
+}.disposed(by: &disposeBag)
+
+formattedDate.subscribe { [weak self] newFormattedDate, oldFormattedDate in
+    // ...
+}.disposed(by: &disposeBag)
+```
+
+A `DisposeBag` is exactly what it says it is, a bag (or array) of disposables.
+
+#### – Observing `Equatable` values
+If you create an Observable which underlying type conforms to `Equtable` you can subscribe to changes using a specific filter. Therefore this pod contains the method:
+```swift
+typealias Filter = (NewValue, OldValue) -> Bool
+
+func subscribe(filter: @escaping Filter, observer: @escaping Observer) -> Disposable {}
+```
+
+Using this method, the observer will only be notified on changes if the corresponding filter matches.
+
+This pod comes with one predefined filter method, called `subscribeDistinct`. Subscribing to an observable using this method, will only notify the observer if the new value is different from the old value. This is useful to prevent unnecessary UI-Updates.
+
+Feel free to add more filters, by extending the `Observable` like this:
+```swift
+extension Observable where T: Equatable {}
+```
