 # StatefulArch
 
-A description of this package.
+ This package contains a set of useful entities to develop scalable iOS applications using either SwiftUI or UIKit along with Combine.
+ 
+## Requirements
+
+- Swift 5.7 or newer
+- iOS 14.0 or newer
+ 
+## Installation
+
+You can install this package using [Swift Package Manager](https://www.swift.org/package-manager/) by adding the following line to the `dependencies` in your `Package.swift` file:
+
+```swift
+.package(url: "https://github.com/purenative/StatefulArch.git", .upToNextMajor(from: "1.0.0"))
+```
+
+## Architecture Overview
+
+StatetefulArch proposes to split screens into independent parts called modules which of them consists of three main components - View, Interceptor and State.
+
+![architecture diagram](Docs/Images/ArchitectureDiagram.png)
+
+### View
+
+View is responsible for user interface and it doesn't contain any business logic or input data validations. Also it delegates user actions processing to Interceptor.
+
+### Interceptor
+
+Interceptor processes user actions received from View and updates State. Interceptor may contain input data validations but it's not responsible for business logic directly. 
+
+*There is another entity in this architecture called Scenario which is responsible for business logic. Scenario isn't displayed on the diagram due to business logic optionality - some screens may not contain business logic such as screens which only consist of static content.*
+
+### State
+
+This entity stores screen's state and determines View's behavior.
+
