Could not understand preferred installation method for optional dependencies

[scotteuser]

Its unclear how to add optional dependencies.

I wanted to test the 'ai' module which has a number of optional dependencies (e.g. 'suggest' in composer.json or other sub-module dependencies enforced by hook_requirements in submodules).

The readme does not make it clear how to do this. I am happy to open a PR to update the readme, but wanted to check if this is the preferred approach:

Once:

1. Clone drupal/recommend-project ddev exec wget https://raw.githubusercontent.com/drupal/recommended-project/refs/heads/11.x/composer.json (or e.g. 10.x)
2. Remove require-dev drupal/core-dev (since that is already part of install instructions) ddev composer remove drupal/core-dev

Every time you install an additional optional dependency:

1. Install desired modules e.g. ddev composer require drupal/ai_provider_openai --dev --prefer-source
2. Run ddev poser
3. Remove the dependency on 'self' from the contrib folder so it does not conflict with the symlinked version in the root ddev exec rm -rf web/modules/contrib/ai

(of course making these commands more generic like PROJECT_NAME to match current docs)
