# Installation {#installation}

Target group: **Administrators**

This extension is part of the TYPO3 Core.

## Installation with Composer {#installation-with-composer}

Check whether you are already using the extension:

```bash
composer show | grep sys-note
```

This should either give you no result or something similar to:

```text
typo3/cms-sys-note       v12.4.9
```

If it is not installed, use the `composer require` command to install the
extension:

```bash
composer require typo3/cms-sys-note
```

The version installed depends on which version of the TYPO3 Core you are using.

## Installation without Composer {#installation-without-composer}

In an installation without Composer, the code of EXT:sys_note is already shipped.
You just have to activate the extension. Head over to the
**Admin Tools > Extensions** module and activate the extension.
