OpenClaw v2026.4.x brings a new curl installer, rootless containers, a Bun CLI-only mode, MoltWorker on Cloudflare, NemoClaw on NVIDIA hardware, and a revamped onboarding wizard. This revised edition of Book 2 in the OpenClaw series rewrites 41+ chapters from the ground up so every command, flag, and config path matches what ships today. Whether you run a laptop, a homelab, a Kubernetes cluster, or an Oracle Always Free VM, this manual walks you from an empty shell to a running, hardened agent.
