To add BLT to a pre-existing Drupal project, do the following:
-
Ensure that your project directory structure is Acquia-cloud compatible by asserting that the Drupal root is in a top-level folder called
docroot
. -
If you currently manage your dependencies via Composer, ensure that they are all up to date via
composer update
. Assert that these updates do not break your project. -
cd
into your existing project directory. -
Add BLT via composer:
composer require acquia/blt:^8.3
-
Continue following instructions for step 2 and beyond in Creating a new project with BLT.
