# How Presets Work?

## Default Behavior

CKEditor Pack automatically creates a separate preset from the default configuration.
This gives you a ready-to-use setup and keeps the original preset unchanged.

## After Modification

All custom changes are stored in your own preset.
The original default configuration stays unchanged.

## After Deletion

If a preset is deleted, the system uses the project default preset automatically.
The editor keeps working without interruption.

## Table of Contents Behavior

The editor follows the allowed tags from the RTE configuration.
If a tag is not allowed, pasted content with that tag is adjusted.

Example:
If `<h1>` is not allowed, pasted `<h1>` content is converted to an allowed format.

## Markdown

When Markdown is enabled, CKEditor Pack can output Markdown instead of HTML.

* Users can write with Markdown shortcuts.
* The Source button shows raw Markdown.
* Markdown supports headings, lists, links, and code blocks.
* Some advanced HTML formatting is limited in Markdown.
* Markdown and Real-time Collaboration do not work together.

## Divider and Break (Separator)

You can remove a divider/break element by double-clicking it.

## Load from YAML

Load from YAML reads the default RTE configuration from TYPO3 core YAML.
It helps integrators quickly restore original settings.

</div>

## Reset

Reset restores modified settings to default values.
This gives a clean baseline and helps avoid configuration issues.

## Sync

Sync aligns values between TYPO3 default RTE YAML and extension custom YAML.
This reduces conflicts and keeps behavior consistent.

## Import / Export Presets

Import/Export Presets helps you share and reuse CKEditor presets across TYPO3 environments.
This keeps local, staging, and live systems consistent.

## Import Presets

Import Presets adds presets from a YAML file into TYPO3.
Upload the YAML file, and the preset is created automatically with toolbar and settings.

</div>

## Export Presets

Export Presets downloads an existing or custom preset as a YAML file.
You can import this file into another TYPO3 system to use the same setup.
