Install via composer
The suggested way to install this Magento 1 Fork is via composer. For this we know of two working installers with support for the magento core as dependency.
Step 1: Create a new composer project
composer initStep 2: Configure composer. The below options are required. You can see all options here.
# Allow composer to apply patches to dependencies of magento-lts
composer config --json extra.enable-patching true
# Configure Magento core composer installer to use magento-lts as the Magento source package
composer config extra.magento-core-package-type magento-source
# Configure the root directory that magento-lts will be installed to, such as "pub", "htdocs", or "www"
composer config extra.magento-root-dir pub
Step 3: Require magento-core-composer-installer
# PHP 7
composer require "aydin-hassan/magento-core-composer-installer":"~2.0.0"
# PHP 8
composer require "aydin-hassan/magento-core-composer-installer":"^2.1.0"
Note: be sure to select y if composer asks you to trust aydin-hassan/magento-core-composer-installer.
Step 4: Require the appropriate version of magento-lts
# Latest tagged v20 series release
composer require "openmage/magento-lts":"^20.0.0"
# Legacy v19 tagged release (Magento 1.9.4.x drop-in replacement supported until April 4, 2025)
composer require "openmage/magento-lts":"^19.4.0"
# Latest on "main" development branch
composer require "openmage/magento-lts":"dev-main"
# Latest on "next" development branch
composer require "openmage/magento-lts":"dev-next"
