Typo3 - Legacy install

Download TYPO3's source package from https://get.typo3.org/:

/var/www/site/$ wget --content-disposition https://get.typo3.org/

Ensure that the package is one level above the web server's document root.

Unpack the typo3_src-11.5.x.tar.gz:

cd public 
 ln -s ../typo3_src-11.5.x typo3_src 
 ln -s typo3_src/index.php index.php 
 ln -s typo3_src/typo3 typo3
