# Configuration Quickstart {#config-quickstart}

Here we explain, how to modify the existing configuration in a few simple steps.

## View Existing Configuration {#view-existing-configuration}

To familiarize yourself with the configuration, look at the existing configuration
in your TYPO3 website:

To view the existing RTE presets in the "Global Configuration", go to
**System > Configuration** in the backend, choose
**$GLOBALS\['TYPO3_CONF_VARS'\] (Global Configuration)** and select
**RTE**:

By default, TYPO3 is shipped with three configuration presets:

-   default
-   full
-   minimal

## Minimal Example {#minimal-example}

Here is a very minimal example of changing the default configuration. All
configuration is done in a custom sitepackage extension, see also
[Use a Sitepackage extension](https://docs.typo3.org/permalink/typo3/cms-rte-ckeditor:best-practice-sitepackage@13.4).

Override the configuration preset "default" by adding this in `<my_extension>/ext_localconf.php`
(replace `my_extension` with your extension key):

```php
$GLOBALS['TYPO3_CONF_VARS']['RTE']['Presets']['default'] = 'EXT:my_extension/Configuration/RTE/Default.yaml';
```

Add the file `Configuration/RTE/Default.yaml` to your extension, use the file
[EXT:rte_ckeditor/Configuration/RTE/Full.yaml (GitHub)](https://github.com/typo3/typo3/blob/13.4/typo3/sysext/rte_ckeditor/Configuration/RTE/Full.yaml) as example.

We explain the example `Minimal.yaml` from the Core:

**EXT:rte_ckeditor/Configuration/RTE/Minimal.yaml**

```yaml
# Load default processing options
imports:
  - { resource: 'EXT:rte_ckeditor/Configuration/RTE/Processing.yaml' }
  - { resource: 'EXT:rte_ckeditor/Configuration/RTE/Editor/Base.yaml' }

# Minimal configuration for the editor
editor:
  config:
    toolbar:
      items:
        - bold
        - italic
        - '|'
        - clipboard
        - undo
        - redo

```

    Imports existing files to make basic parts reusable and improve structure of configuration
