 ## About
 
-Kakarot is an (zk)-Ethereum Virtual Machine implementation written in Cairo.
-Kakarot is Ethereum compatible, i.e. all existing smart contracts, developer
-tools and wallets work out-of-the-box on Kakarot. It's been open source from day
-one. Soon available on Starknet L2 and Appchains.
+Kakarot is a state-of-the-art (zk)-Ethereum Virtual Machine implementation written in Cairo. It brings the power of Ethereum's ecosystem to Starknet while maintaining complete compatibility with existing smart contracts, developer tools, and wallets. Built with a focus on performance, security, and developer experience, Kakarot enables seamless deployment of Ethereum contracts on Starknet L2 and Appchains.
 
-🚧 It is a work in progress, and it is not ready for production.
+🚧 **Note:** This project is under active development and not yet ready for production use.
