+This repository allows you to quickly install Apache Solr for Drupal 9 into a [Ddev](https://ddev.readthedocs.io) project using just `ddev get drud/ddev-drupal9-solr`. It follows the [Setting up Solr (single core) - the classic way](https://git.drupalcode.org/project/search_api_solr/-/blob/4.x/README.md#setting-up-solr-single-core-the-classic-way) recipe.
 
 ## Installation on Drupal 9
 
 1. `ddev get drud/ddev-drupal9-solr && ddev restart`
 1. You may need to install the relevant Drupal requirements: `ddev composer require drush/drush:* drupal/search_api_solr`
-1. Enable the Search API Solr Search Defaults module: `ddev drush en -y search_api_solr_defaults`. (If it can't be enabled due to the "article" content type not existing, you can just create a search_api_solr server manually.)
-1. Edit the enabled search_api server named `default_solr_server` at `admin/config/search/search-api/server/default_solr_server/edit`
-   * set "Solr host" to `solr`

 ## Caveats
 * This recipe won't work with versions of solr before solr:8, and Acquia and Pantheon.io hosting require versions from 3 to 7. You'll want to see the [contributed recipes](https://github.com/drud/ddev-contrib) for older versions of solr.
