 ## What is Fun?
 
-Fun is an experiment, just for fun, but Fun works!
+Fun is a small, strict, and simple programming language that runs on a compact stack-based virtual machine. The C core is intentionally minimal; most functionality and standard libraries are implemented in Fun itself.
 
-Fun is a highly strict programming language, but also highly simple. It looks like Python (My favorite language), but there are differences.
+Fun is dynamically typed with optional static type annotations, <a href="/features/">featuring first-class functions</a>, classes with inheritance, pattern matching, and a rich standard library. It supports everything from basic scripting to TCP sockets, serial communication, threading, cryptography (MD5, SHA-1/256/384/512, CRC-32, AES-256), and a built-in debugger.

-- Type safety
-- Written in C (C99) and Fun
-- Internal libs are written with no_camel_case even when written in Fun, except class names
-- Only a minimal function set is written in C, and most other core functions and libraries are implemented in Fun
+- **Dynamic typing** with optional **static type annotations** (`number`, `string`, `boolean`, `float`, `byte`, `uint8`&ndash;`uint64`, `int8`&ndash;`int64`)
+- **Stack-based bytecode VM** written in C99 with ~220 opcodes
+- **First-class functions**, anonymous functions (`fn`), and higher-order operations (`map`, `filter`, `reduce`)
+- **Classes** with constructors, methods, and single inheritance
+- **Exception handling** with `try`/`catch`/`finally`
+- **Built-in data structures**: arrays (with slicing), maps/objects, strings
+- **Concurrency**: threads (`thread_spawn`, `thread_join`) and cooperative async scheduler
+- **Networking**: TCP and Unix domain sockets with non-blocking I/O polling
+- **Serial communication**: full termios-based serial port control
+- **Cryptography**: pure-Fun implementations of MD5, SHA-1/256/384/512, CRC-32/CRC-32C, AES-256 ECB
+- **Built-in debugger** with breakpoints, step/next/finish, and stack inspection
+- **Minimal C core** &mdash; most standard libraries are implemented in Fun itself

 <h2>What is Fun?</h2>
 
-<p>Fun is an experiment, just for fun, but Fun works!</p>
+<p>Fun is a small, strict, and simple programming language that runs on a compact stack-based virtual machine. The C core is intentionally minimal; most functionality and standard libraries are implemented in Fun itself.</p>
 
-<p>Fun is a highly strict programming language, but also highly simple. It looks like Python (My favorite language), but there are differences.</p>
+<p>Fun is dynamically typed with optional static type annotations, <a href="/features/">featuring first-class functions</a>, classes with inheritance, pattern matching, and a rich standard library. It supports everything from basic scripting to TCP sockets, serial communication, threading, cryptography (MD5, SHA-1/256/384/512, CRC-32, AES-256), and a built-in debugger.</p>
