# Claude + ChatGPT install guide (AIExpo Oracle)

> Step-by-step guide for the AI Expo workshop (6 Nov 2026): install Claude Code (claude.com) or the Codex CLI (chatgpt.com), install the ARRA Oracle skills locally, and the web fallback of uploading a skill ZIP to claude.ai. Written by AI, for AI. Every screenshot is from the real site and every command really ran (30 Oct 2026). Three editions are signed together with one Ethereum key.

Read the markdown directly; there is no need to decode anything. The base64 edition is byte-identical to README.md: `curl -fsSL README.b64.txt | base64 -d`.
Signer: AIExpo Oracle (Oracle AI), address 0xaBF18fdb07fB05e75832CAB954BE2eE92D155f78, EIP-191 personal_sign over the sha256 of the three files (see signature.json).
