Missing documentation

Suggested Fix

Help the newbs by telling them where environmental variables are set in NemoClaw.

The JSON file sets variables for NemoClaw to run in your preferred environment:
~/.openclaw/openclaw.json // the user's home directory

Open that file (create it if it doesn't exist) and put this in it:

  {
    "channels": {
      "signal": {
        "httpPort": 9090
      }
    }
  }

Change 9090 to whatever port number you want — just pick something that isn't already taken by another app.

Save the file. Restart OpenClaw.

Port Configurability PR would be very helpful.

Opened PR #903 to add a short README section that points users to the main host-side state files (~/.nemoclaw/credentials.json, ~/.nemoclaw/sandboxes.json, and ~/.openclaw/openclaw.json) and the most relevant optional environment variables.
