# Quick start

## Before class

* Use a projector for teacher-led modes.
* For self-paced or live interaction, confirm that learners can use a phone, tablet, or computer and can open the public site on the school network.
* The English demo is fixed to grades 10–12. Choose a topic and 10, 20, or 30 minutes; the site recommends 2, 4, or 6 cases.
* Review every selected case. Add, remove, or replace cases before starting.
* Read the [pilot safety notice](/message-unpacked-docs/en/sensitive-content.md) and adjust the selection for your class.

## Choose a delivery path

Use a **static activity link** when learners can answer independently or the class can share one projected screen. Static links need no classroom backend and do not transmit answers.

Use **live classroom interaction** when you want anonymous class-level answer counts and distributions. The teacher projects the full case; learner phones show only the number and choices.

## Test once

1. Open the generated link or room on the teacher device.
2. Join from a second device or private browser window.
3. Complete one case, reveal the explanation, and verify that official links are reachable from the school network.
4. Keep a static projector link ready as the fallback for live mode.
