You can load this example data to try out the site package extension.
Create a brand-new TYPO3 installation, for example with DDEV and composer:
:ref:`Installing TYPO3 with DDEV <t3start:installation-ddev-tutorial>`
Install the :composer:`t3docs/site-package` extension.
Install the :composer:`t3docs/site-package-data` extension.
Import the Example Site data by running the console command vendor/bin/typo3 extension:setup.
After importing the example data you can safely remove this extension again.
With DDEV the following commands would be needed:
ddev composer req t3docs/site-package
ddev composer req t3docs/site-package-data
ddev typo3 extension:setup
ddev composer remove t3docs/site-package-data
