# How Luce works: events, phases, modes and screens

> The ideas behind Luce: an event moves through phases, modes decide what guests' phones show in each, and you drive them from the console and the big screen.

Luce is built on a few ideas that appear on every screen: the event and its status, the phases of the show, the modes that fill them, and the screens that show them. Knowing these makes the rest of the docs quicker to follow.

## The event and its status

An event moves through these statuses, shown at the top of the console:

| Status | What it means |
| - | - |
| **Draft** | Only you and your team see it. Phones cannot join yet, but you can set up and rehearse everything. |
| **Not started** | Published. Guests can open the page and answer. Phones join when the event starts and open with what you set up. |
| **Live** | The show is on. Phones in the show follow the mode on air. |
| **Ended** | The show is over. Phones go back to the event page, which shows the event as over. |
| **Cancelled** | The event was taken down. |

Ending the show with **End show** cannot be undone.

## The event page

Every event has a page with its own short link. Guests read the details there, answer **Going** or **Maybe**, and open the same page on their phone to join the show.

## Phases and modes

A mode is one thing your show does. Modes are grouped by the phase they belong to, and guests see a mode only in its own phase:

| Phase | Modes |
| - | - |
| **Before the event** | Intro |
| **During the event** | Story, Manual, Auto, Gyro, Ambient, Pulse, Fan cam |
| **After the event** | Outro |
| **Around the event** | Big screen, Timekeeper, Overlay, Agenda, Good to know, Wish list, Sponsors |

During the event, one mode is **on air** at a time. You choose it in the console with **Set on air**, and every phone in the show switches to it.

## The console

The console is where you set up and run the event. The list on the left holds your modes by phase, the middle shows the selected mode, and the side panel holds the event's details, guests and tasks. The preview shows what a guest's phone shows, or what the big screen shows.

## A guest's phone

Guests join from their phone's browser, with no app to install. In the show, the phone shows whatever the mode on air sends: a reel, a colour, a picture or a video.

## The big screen

The big screen is the venue's screen or projector. Open `luce.show/screen` on the computer that drives it and type the code shown in the console's Big screen mode, or open the screen link from there. It can show the join code, a countdown, a message, your media, polls and the guest on Fan cam.

## Show capacity

The show capacity is how many phones can join the live show at once. Anyone can still open the event page and answer. When you publish, the capacity is taken from your plan's people for the month.
