Getting Started

We've put together this starter project to help you get started quickly, using contracts already deployed to either testnet or Celo mainnet. The project provides: a storage example, how to iterate through a subgraph. 

Advanced developers can use Celo Composer from command-line to customize exactly what platform you want to build for: React, React Native (with or without Expo integration), Angular, or Flutter. It includes a Subgraph integration if you need it.
