 Let's overview the **general state of iOS accessibility** and get familiar with relevant system **resources**, **features** and **tools**.
 
 ### History of iOS Accessibility
-[**"A Timeline of iOS Accessibility: It Started with 36 Seconds"**](https://www.macstories.net/stories/a-timeline-of-ios-accessibility-it-started-with-36-seconds/) is a marvellous research done by **Shelly Brisbin** that covers the **path Apple has been going to make their devices accessible**. From the very beginning of iPhone story at 2007 to the current moment.

 ### Current moment
 Starting from *“We also care greatly about accessibility”* at June 8, 2009 Apple hasn't stopped for a second in promotion of **designing with accessibility in mind**.
 
 ### Accessibility and inclusion
-**Accessibility is the engine of people with disabilities inclusion.** Apple claims [**inclusivity**](https://www.apple.com/diversity/) of their products to be **one of the company core values** and puts [**unmeasurable efforts**](https://www.apple.com/accessibility/) into support of *disabilities community* and advancement of **assistive technology**.

 - product design means focused on delivering **inclusive user experience**;
 - guidance for Apple developers on how to integrate applications with **assistive technology**.
 
 ### Accessibility features
-Apple assistive technology is known as accessibility features. Accessibility features are native software solutions aimed to *"personalise how users interact with their devices in ways that work for them"*.
+Apple assistive technology is known as [**accessibility features**](https://support.apple.com/en-gb/guide/iphone/iph3e2e4367/ios)). Accessibility features are **native software solutions** aimed to *"personalise how users interact with their devices in ways that work for them"*.
 
-Accessibility features stack provides similar user experience over various Apple platforms. In persective of the book we are going to discuss iOS accessibility kit, but the knowledge of these particular features can be extrapolated on other systems which have the appropriate functional.
+Accessibility features are available for *various* Apple platforms. In perspective of the book we are going to discuss **iOS accessibility kit**, but the knowledge of these particular features can be extrapolated to **other systems** which have the mentioned functional.
 
-For example, VoiceOver, which is Apple screenreader, is available on all company's platforms for devices equipped with displays -- not only  iOS, but also macOS, iPadOS, tvOS, watchOS and visionOS.

 ### Accessibility of iPadOS
 iPadOS is *very* similar to iOS, excluding features related to **multitasking** -- running multiple apps at once, and **expansibility** -- connecting external devices. 
 
-So keep in mind that **everything you learn about iOS accessibility features is also applicable to iPadOS**.

-Despite [**iOS Accessibility Handbook**](<doc:iOSAccessibilityHandbook>) name, we *are* going to discuss a few moments **exclusive for iPads**. For example, in [**Full Keyboard Access**](<doc:FullKeyboardAccess>), which is also present on iPhones, but the **functionality** slightly differs.

+### Functionality approach
+iOS may not be here in the (distant) future, but your deep understanding of **interface theory** will stay and be applicable. Technology advances rapidly, invest in **functionality expertise** -- not platform one.

 ### Yearly accessibility updates
-Annually, on 16th of May, which is **GAAD** (**G**lobal **A**ccessibility **A**wareness **D**ay), Apple publishes [**updates on accessibility**](https://www.apple.com/newsroom/search/?q=global+accessibility+awareness+day) of their products. New accessibility features are usually announced this way.

The *principles* behind functionality of various **assistive technology** are shared, but it is *vital* to **recognise** them and have a **clear understanding** of what we work on.

+- As an operational system, iOS is **one of the most accessible solutions** available on the market. Accessibility is Apple's **core value** and the company responds to their claims.
+- **Assistive technology** functionality of iOS is represented by **accessibility features**, which include various software applications dealing with a **broad spectrum of disabilities**.
+- **New accessibility features** are continually introduced.
+- Different accessibility features work with the **same interface**, so it is possible to handle such variety of software by learning its **working principles**.
 
-To dive right into the process of **developing accessible applications** don't hesitate to open the [**iOS Accessibility Guide**](https://vodgroup.github.io/AccessibilityDocumentation/tutorials/adaptionstrategy) map. *Everything* is there.
