 ## Robust C by default
 **A dialect of C with `defer` and automatic zero-initialization.**
 
-Prism is a single-file transpiler that makes C safer without changing how you write it.
+Prism is a lightweight and very fast transpiler that makes C safer without changing how you write it.

 - **Building Real C** — OpenSSL, SQLite, Bash, GNU Coreutils, Make, Curl
 - **Proper transpiler** — tracks typedefs, respects scope, catches unsafe patterns
 - **Opt-out features** Disable parts of the transpiler, like zero-init, with CLI flags
