Distributions were created to give new users easy access to a preconfigured installation of TYPO3 that they could then use without the need to set up and configure various parts of the CMS such as page structure, content and templating.
The following is only true, if you installed TYPO3 without Composer:
When installing TYPO3 for the first time, you will be given the option to access a set of “Preconfigured Distributions” once the installation is complete. Upon selecting this option, you will be redirected to your installations “Extension Manger” and given a list of Distributions to choose from.
For an existing installation of TYPO3, distributions are already available and can be accessed in the Extension Manager.
If you installed TYPO3 via Composer, all extensions and distributions will need to be installed and managed via Composer.
The Introduction Package is a complete, fully operational website. It it based on a responsive design using bootstrap templates and contains example content for testing and evaluation. This is ideal for new users who wish to have a “look around” and get more familiar with the CMS.
To install the introduction package, follow the instructions in Install Introduction Package.
The steps for installing a distribution with Composer are the same as installing an extension with Composer. See the section Install an Extension With Composer if you wish to install additional extensions. You can also find more information in that section.
