[Lodestar](https://lodestar.chainsafe.io) is a TypeScript implementation of the [Ethereum Consensus specification](https://github.com/ethereum/consensus-specs) developed by [ChainSafe Systems](https://chainsafe.io).
## Getting started
- :gear: Follow the instructions for [build from source](https://chainsafe.github.io/lodestar/run/getting-started/installation#build-from-source), [binaries](https://chainsafe.github.io/lodestar/run/getting-started/installation#binaries), or [Docker](https://chainsafe.github.io/lodestar/run/getting-started/installation#docker-installation) to install Lodestar. Or use our [Lodestar Quickstart scripts](https://github.com/ChainSafe/lodestar-quickstart).
- :books: Use [Lodestar libraries](https://chainsafe.github.io/lodestar/supporting-libraries/libraries/) in your next Ethereum Typescript project.
- :globe_with_meridians: Run a beacon node on [mainnet or a public testnet](https://chainsafe.github.io/lodestar/run/beacon-management/starting-a-node/).
- :computer: Utilize the whole stack by [starting a local testnet](https://chainsafe.github.io/lodestar/contribution/advanced-topics/setting-up-a-testnet/).
- :spiral_notepad: View the Lodestar [CLI commands and options](https://chainsafe.github.io/lodestar/reference/cli/).
