# Getting started

Citrea is the first rollup that enhances the capabilities of Bitcoin blockspace with zero knowledge technology. Citrea is the only scalability solution that uses Bitcoin both as a data availability and a settlement layer, via its BitVM-based trust-minimized two-way peg program - [Clementine](https://docs.citrea.xyz/essentials/clementine-trust-minimized-bitcoin-bridge). Citrea is fully EVM compatible, enabling all EVM developers to easily build on Bitcoin.

This documentation serves as a knowledge base for both developers and users. If you're a developer, you can check our [developer documentation](https://docs.citrea.xyz/developer-documentation/developer-documentation), and if you're a user, you can start using the Citrea Mainnet by [bridging to Citrea](https://citrea.xyz/bridge). Along with that, you can check our architecture and security properties from the links in the sidebar.
