+

+
+`ddev drush` is fully supported, along with using or testing MariaDB, MySQL, and PostgreSQL databases (and Sqlite3)
+
+
+```
+git clone https://git.drupalcode.org/project/drupal.git drupal
+cd drupal
+ddev config --project-type=drupal
+ddev get justafish/ddev-drupal-core-dev
+ddev restart
+ddev composer install
+ddev config --update
+
+
+# Install drupal
+ddev drush si -y --account-pass==admin
+
+# Run PHPUnit tests
+ddev phpunit core/modules/sdc
+
+# Run Nightwatch tests (currently only runs on Chrome)
+ddev nightwatch --tag core
+```
+
+## Using various database types
+
+By default, the DDEV default database type is used (MariaDB).
+
+To use another supported database type,
+`ddev delete -Oy` and `ddev config --database=mysql:8.0` or `ddev config --database=postgres:16` for example.
+
+To use Sqlite,
+```
+ddev stop
+ddev config --disable-settings-management --omit-containers=db
+rm -rf web/sites/default/settings*.php web/sites/default/files
+ddev start
+ddev drupal install
+```
