DDEV simplifies integrating the power and consistency of containerization into your workflows. Set up environments in minutes; switch contexts and projects quickly and easily; speed your time to deployment. DDEV handles the complexity. You get on with the valuable part of your job.

Before proceeding, make sure your DDEV installation is up to date.

In a new project folder using your favorite shell, run these lines:

ddev config --project-type=typo3 --docroot=public --create-docroot --php-version 8.1
ddev composer create --no-install "typo3/cms-base-distribution:^12"
ddev composer install
ddev restart
ddev exec touch public/FIRST_INSTALL
ddev launch

If you are experienced with Composer you can create your own composer.json and select the needed packages of TYPO3 via the Composer Helper. Instead of the ddev composer create command above, run the command created with the Composer Helper prepended with ddev. E.g.:

ddev config --project-type=typo3 --docroot=public --create-docroot --php-version 8.1
ddev composer require "typo3/cms-core:^12" "typo3/minimal:^12" ...
ddev typo3cms install:setup (if the TYPO3 Console is installed)
ddev launch
composer create-project "typo3/cms-base-distribution:^12" my-new-project

If you are experienced with Composer you can create your own composer.json and select the needed packages of TYPO3 via the Composer Helper.

Using wget 
wget --content-disposition https://get.typo3.org/12.3.0
Using cURL (e.g., when wget fails with SSL error) 
curl -L -o typo3_src.tgz https://get.typo3.org/12.3.0

In case you are encountering SSL warnings (host name mismatch), please make sure that you are using a client that supports Server Name Indication (SNI). This especially affects old versions of wget (before version 1.14).

Package Signatures - Verifying integrity of releases

TYPO3 Release Packages (the downloadable tarballs and zip files) as well as Git tags are signed using PGP signatures since TYPO3 v7 during the automated release process. Besides that, SHA1 and SHA2-256 hashes are being generated for these files. Find more details on verifying signatures and hashes in the infrastructure guide.
