### TL;DR

**sui.direct** is a decentralized version control system on the SUI blockchain — like an "on-chain GitHub." It uses [Walrus ](https://walrus.xyz/)for storing data, supports public and local nodes for decentralization, and offers a user-friendly experience through its **website** and **command-line tool (CLI)** for easy use.
