Lesson 4: Launch Day – Domain, Settings, and Rollback Plan
Lesson Objectives
By the end of this lesson, students should be able to:
- Connect a business-owned custom domain.
- Switch test settings to live safely.

Lesson Content
Launch checklist:
- Domain: buy in the business's registrar account; connect it using the builder's instructions (usually adding DNS records). Custom domains often require a paid plan.
- Live settings: switch payment providers from test mode to live mode; remove sample data; confirm email sender details.
- Final checks: run the test plan once more on the live link.
- Rollback plan: note the last good version and how to restore it.
- Support plan: how users report problems (an email or form) and who responds.
- Announce: start with a small group before announcing widely.
