 ## PixelCanvas: Decentralized Collaborative Pixel Art Smart Contract
 
 ### Contract Overview
-A collaborative on-chain pixel art platform implemented as an Ethereum smart contract, enabling users to create and modify a shared 64x64 pixel canvas.
+PixelCanvas is an Ethereum smart contract that enables collaborative pixel art creation on a fixed 64x64 canvas with a predefined color palette.
