# Linking Composer packages and TYPO3 extensions {#linking-extensions}

You can use the text role `:composer:` to create an infobox with information
and links to Packagist. This way you can link to any TYPO3 extension
that is also listed on Packagist like [`georgringer/news`](https://packagist.org/packages/georgringer/news) and
[`b13/container`](https://packagist.org/packages/b13/container), any TYPO3 system extension like
[`typo3/cms-adminpanel`](https://packagist.org/packages/typo3/cms-adminpanel) and any other Composer package like
[`typo3/testing-framework`](https://packagist.org/packages/typo3/testing-framework):

```rst
This way you can link to any TYPO3 extension
that is also listed on packagist like :composer:`georgringer/news` and
:composer:`b13/container`, any TYPO3 system extension like
:composer:`typo3/cms-adminpanel` and any other Composer package like
:composer:`typo3/testing-framework`
```

If you want to link to the TYPO3 Extension Repository (TER) you can use the
text role `t3ext` instead and link extensions like [EXT:news](https://extensions.typo3.org/extension/news) or
system extensions like [EXT:adminpanel](https://extensions.typo3.org/extension/adminpanel):

```rst
You can use the text role `t3ext` instead and link extensions like
:t3ext:`news` or system extensions like :t3ext:`adminpanel`
