Check each one yourself:\n- Rex's Linux server from the preview channel, running as `exedev` and back after a reboot\n- The server on your tailnet as `my-rex` once you open its Tailscale sign-in link\n- Claude Code and Codex using exe.dev's LLM integration, with Rex's agent skill installed\n- A Rex session `work` in `~/project` where Claude Code answers `OK`\n\nRun the VM-side commands in \"Set up the VM\" only; skip creating the VM.\nIf `exeuntu configure` reports an existing user config, leave it alone.\nIf `~/project` already exists, leave it alone. Don't start interactive\nagents. Verify with the checks at the end of that section: the service\nis active, `rex version` starts with `rex 0.1.0`, and the `work` session\nshows `OK` from Claude Code. Skip the later sections and the FAQ.\nFinish by giving the owner the Tailscale sign-in link from\n`rex server status` (the `authenticate:` line), and tell them to open it\nsigned in to the tailnet their Mac is on, check that MagicDNS and HTTPS\ncertificates are on for that tailnet, then add\n`https://\u003cthis VM's name\u003e.\u003ctailnet\u003e.ts.net` in Rex for Mac with\n**Add Remote Host…** (\"Add it to Rex for Mac\").
