> Official Zesu documentation: getting started, concepts, configuration, and CLI reference for the Consensys stateless ZK execution client.

This file contains links to documentation sections following the llmstxt.org standard.

## Table of Contents

- [Introduction](https://docs.zesu.consensys.io/docs.md): Introduction to Zesu, the stateless EVM block executor that generates block-validation proofs for EVM-compatible chains.
- [Obtain the guest program](https://docs.zesu.consensys.io/get-started/get-guest-program.md): Where to get the Zesu zkVM guest program artifact and how to integrate it into a zkVM host.
- [Install the native Zesu binary](https://docs.zesu.consensys.io/get-started/install-native.md): Install build prerequisites and compile the native Zesu binary that runs Ethereum block execution on your host CPU.
- [Architecture](https://docs.zesu.consensys.io/concepts/architecture.md): How Zesu fits into the zkVM proving pipeline and why it is built as a relocatable ELF object.
- [Inputs and outputs](https://docs.zesu.consensys.io/concepts/inputs-and-outputs.md): The stateless input Zesu consumes and the validation result it produces, as defined by EIP-8025.
- [Witness retrieval](https://docs.zesu.consensys.io/concepts/witness-retrieval.md): What an execution witness is, why Zesu needs one, and how Zesu retrieves it from an execution client.
- [CLI options](https://docs.zesu.consensys.io/reference/cli-options.md): Command-line options, environment variables, output streams, and exit codes for the native Zesu binary.
- [Glossary](https://docs.zesu.consensys.io/reference/glossary.md): Glossary of terms used across the Zesu documentation.
- [zkVM symbol reference](https://docs.zesu.consensys.io/reference/zkvm-symbols.md): Complete reference for the extern symbols that zkVM hosts must implement to integrate the Zesu guest program.
