Worked on enhancing the Ethereum Prover CLI documentation for the matter-labs/zksync-os repository, focusing on improving clarity around CPU and GPU proving workflows. Applied technical writing and documentation best practices using Markdown to detail explicit VRAM requirements and differentiate between CPU and GPU commands. The updates aligned the documentation with actual usage patterns, reducing onboarding time for new developers and minimizing support queries. By clarifying command usage and hardware requirements, the work improved the reliability of developer tooling and streamlined contributor onboarding. The changes supported maintainers in guiding new contributors and ensured the documentation accurately reflected the Ethereum proving process.
