Before installing Univer Slides, learn the four concepts that shape every Slides integration:

* Plugin
* Snapshot and data model
* Command
* Facade API

## Basic Concepts

### Plugins

Univer Slides is assembled from plugins. `UniverSlidesPlugin` registers the `UNIVER_SLIDE` presentation model and its core commands, while `UniverSlidesUIPlugin` adds the browser editor UI. Add optional packages such as print, tables, charts, or import and export only when your application needs them.

The Slides UI uses Docs, Drawing, and Shape services internally to edit text and graphics. These are technical dependencies of the Slides plugin stack; you do not need prior experience with another Univer product.

### Snapshot and data model

One presentation is persisted as an [`ISlideData` snapshot](https://docs.univer.ai/guides/slides/model/slide-data.md). `name` and `defaultPageSize` describe the presentation, `slideOrder` orders the entries in `slides`, and optional reusable layers live in `masterPages` and `layoutPages`.

Use `presentation.save()` to read the current snapshot. A snapshot is persistence data, not a live model, so changing the snapshot object after the presentation starts does not update the editor.

### Command

Runtime changes are executed through commands. Commands keep model validation, view updates, and undo and redo in the same change pipeline. Slides Facade methods prepare command parameters and execute those commands for you.

> [!WARNING: Caution]
> Do not mutate a running presentation's snapshot directly. Use Slides Facade methods or registered commands.

### Facade API

Import `@univerjs-pro/slides/facade` after the core Facade entry to add Slides APIs to `FUniver`. The entry provides methods such as `createPresentation()`, `getActivePresentation()`, and `getPresentation()`.

See [Using the Slides Facade API](https://docs.univer.ai/guides/slides/getting-started/facade.md) for the complete setup and examples.
