# Saving and publishing changes

> How your work is saved, how undo and redo protect you along the way, and how to take a theme live once you're happy with it.

The visual builder is designed to let you experiment freely and commit confidently. Your changes are tracked as you work, kept reversible, and only written to your theme when you choose to save.

## Undo and redo

Every change you make—adding an element, editing a style, updating a setting, enabling dark mode—is recorded in your editing history. If something doesn't look right, step back with **Undo**, or step forward again with **Redo**. The builder keeps a generous history, so you can explore without fear of losing your place.

## Saving your changes

Changes stay in your session until you click **Save**. What happens then depends on the kind of theme you're editing:

### Trial themes

Saving a trial theme stores your work safely in your Zenplates account. Trial themes aren't visible to your visitors, so they're the ideal place to keep refining a design over multiple sessions before committing it to Zendesk.

### Installed themes

Saving an installed theme writes your changes—templates, styles, settings and assets—directly back to that theme in your Zendesk theme library. The theme is updated in place, but the changes only reach your visitors once the theme is **active**.

## Going live

Making a theme live is done in Zendesk, which keeps you in full control of when changes are published:

1. Save your work in the visual builder.

2. If you've been working on a trial theme, install it to add it to your Zendesk theme library. Installing requires a Developer license, so use **Buy now** on the theme if you don't have one yet.

3. Open the Zendesk [Theming Workbench](https://support.zendesk.com/hc/en-us/articles/4408824139546-Branding-your-help-center)—use **View in Workbench** in the theme's menu on the dashboard—and [activate the theme](https://support.zendesk.com/hc/en-us/articles/4408828836250-Changing-the-live-theme-of-your-help-center) to publish it to your help center.

Because the builder always produces a standard Zendesk theme, you keep full ownership of the result and can manage it in Zendesk just like any other theme.
