# Resources To aid in the development process, we've created several valuable resources: * Play with our [test environment](https://dev.testnet.governance.vebetterdao.org/)\ Utilize our testnet environment to add apps to the ecosystem, interact with smart contracts, and manage reward distribution. Detailed information about the test environment can be found in its [dedicated section](#test-environment), providing you with a sandbox to refine and test your applications before going live. * [VeChain Kit](https://vechain-kit.vechain.org/): an all-in-one javascript library for building VeChain applications. * Read the [Integration](/developer-guides/get-started.md) and the [Sustainability Proofs](/developer-guides/sustainability-proof-and-impacts.md) sections to understand how to distribute B3TR tokens * **X-App-Template** ()\ This template serves as a foundational guide to help you code your app and interact effectively with VeBetter. It's a demo of an app where you can scan grocery receipts and be rewarded if you buy sustainably. * [Vechain Getting Started Documentation](https://docs.vechain.org/developer-resources/getting-started)\ Documentation of everything you need to know about vechain and blockchain technology to create a decentralized app. * [VeBetter contracts](https://github.com/vechain/vebetterdao-contracts)\ A package containing all the smart contracts used in mainnet. You can also install this repository as a dependency in your project and use it to access the ABIs of the contracts and their addresses. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
