+## Why Rust?
 
-**Note: this README is for _users_ rather than _contributors_.**
-If you wish to _contribute_ to the compiler, you should read
-[CONTRIBUTING.md](CONTRIBUTING.md) instead.
+- **Performance:** Fast and memory-efficient, suitable for critical services, embedded devices, and easily integrate with other languages.
 
-<details>
-<summary>Table of Contents</summary>
+- **Reliability:** Our rich type system and ownership model ensure memory and thread safety, reducing bugs at compile-time.
