* Lux Lab is connected to an instance. For instructions, see [Connect Lux Lab to an instance](https://www.servicenow.com/docs/Gpk7TWpehNlrHWy1LsWnwA "Connect Lux Lab to your ServiceNow instance so that you can access instance files, deploy changes, and preview your work. Instance sign-in is required before you can reach the app.").
