+# About Swift
+
+Understand the high-level goals of the language.
+
+Swift is a fantastic way to write software
+for phones, tablets, desktops, servers,
+or anything else that runs code.
+It's a safe and fast programming language
+that combines the best in modern language thinking
+with wisdom from a diverse open source community.
+
+Swift is friendly to new programmers,
+without sacrificing the power and flexibility
+that experienced programmers need.
+It's an industrial-quality programming language
+that's as expressive and enjoyable as a scripting language.
+The compiler is optimized for performance
+and the language is optimized for development,
+without compromising on either.
+
+Swift defines away large classes of common programming errors
+by adopting modern programming patterns:
+
+- Variables are always initialized before use.
+- Array indices are checked for out-of-bounds errors.
+- Integers are checked for overflow.
+- Optionals ensure that `nil` values are handled explicitly.
+- Memory is managed automatically.
+- Error handling allows controlled recovery from unexpected failures.
+
+Swift code is compiled and optimized to get the most out of modern hardware.
+The syntax and standard library have been designed
+based on the guiding principle that
+the obvious way to write your code should also perform the best.
+Its combination of safety and speed make Swift an excellent choice for
+everything from "Hello, world!" to an entire operating system.
+
+Swift combines a modern, lightweight syntax
+that's familiar for developers coming from other popular languages
+with powerful features like type inference and pattern matching,
+allowing complex ideas to be expressed in a clear and concise manner.
+As a result, code is easier to read, write, and maintain.
+
+Swift continues to evolve with thoughtful new features and powerful capabilities.
+The goals for Swift are ambitious.
+We can’t wait to see what you create with it.
