# Introduction {#rte-backend-introduction}

When you configure a table in `$TCA` and add a field of the type "text"
which is edited by a `<textarea>`, you can choose to use a Rich Text
Editor (RTE) instead of the simple form field. An RTE enables the users
to use visual formatting aids to create bold, italic, paragraphs,
tables, etc.

For full details about setting up a field to use an RTE, please refer to the
chapter labeled 'special-configuration-options' in older versions of the
TCA Reference.

The short story is that it's enough to set the key `enableRichtext` to true.

```php
'poem' => array(
    'exclude' => 0,
    'label' => 'LLL:EXT:examples/locallang_db.xlf:tx_examples_haiku.poem',
    'config' => array(
        'type' => 'text',
        'cols' => 40,
        'rows' => 6,
        'enableRichtext' => true
    ),
),
```

This works for FlexForms too:

```xml
<poem>
    <TCEforms>
        <exclude>0</exclude>
        <label>LLL:EXT:examples/locallang_db.xlf:tx_examples_haiku.poem</label>
        <config>
            <type>text</type>
            <cols>40<cols>
            <rows>6</rows>
            <enableRichtext>true</enableRichtext>
        </config>
    <TCEforms>
</poem>
```

> [!IMPORTANT]
> Don't forget to enable Rich Text Editor in the back end,
> in User Settings -> Edit and Advanced functions,
> check "Enable Rich Text Editor", if not already done.
