With Composer or without?

With Composer

The recommended way of installing TYPO3 is via the PHP package manager Composer. For detailed instructions on how to install TYPO3 with Composer, visit the Install TYPO3 via Composer section of this manual.

When you install with Composer, you will install the core extensions and third party extensions with the package manager Composer on the command line. You will not be able to import extensions (e.g. from TER) in the TYPO3 backend via the browser!

Without Composer

If you do not have access to Composer, you can install TYPO3 by downloading and then extracting its source package on your web server.

Directions for installing TYPO3 without Composer can be found in Install TYPO3 without Composer.

Which File Format to Use

Tip

This is only relevant if you install TYPO3 without Composer!

The TYPO3 Source package is available as a .zip or .tar.gz distribution. Their content is the same and you should download the one that you will be able to extract directly on your web server (Windows based systems are more likely to use the .zip file while Linux distributions tend to use the .tar.gz file).
