## EVM-XCM Jungle Toolkit

- [Introduction](https://jungle-toolkit.gitbook.io/evm-xcm-jungle-toolkit/introduction.md)
- [What is the EVM-XCM Jungle Toolkit?](https://jungle-toolkit.gitbook.io/evm-xcm-jungle-toolkit/introduction/what-is-the-evm-xcm-jungle-toolkit.md): The EVM-XCM Jungle Toolkit is a collection of several tools, guides, libraries & code snippets allowing developers to create more easily modern cross-chain Polkadot-based dApps leveraging EVM.
- [Why use this toolkit?](https://jungle-toolkit.gitbook.io/evm-xcm-jungle-toolkit/introduction/why-use-this-toolkit.md): The Jungle Toolkit allows developers to easily connect tools that have never been connected before, pushing the boundaries of what cross-chain dApps on Polkadot are really capable of.
- [Who is this toolkit made for?](https://jungle-toolkit.gitbook.io/evm-xcm-jungle-toolkit/introduction/who-is-this-toolkit-made-for.md): This toolkit has been created while keeping in mind the importance of simplicity. An intermediate understanding of blockchain development is still required to fully master this material.
- [What tools are this toolkit made of?](https://jungle-toolkit.gitbook.io/evm-xcm-jungle-toolkit/introduction/what-tools-are-this-toolkit-made-of.md): The Jungle Toolkit is created using a large number of amazing tools and technologies. Our goal is to connect libraries, SDK & blockchains, both from the EVM & DOT worlds.
