Suggestion for: What are basic pages?

I think the problem was that the DDEV instructions are:
1. Clone or create the code for your project.
2. cd into the project directory and run ddev config to initialize a DDEV project.
3. Run ddev start to spin up the project.
4. Run ddev launch to open your project in a browser.

BUT in betweeh steps 3 & 4, the user needs to run:
ddev composer create drupal/cms

So the DDEV and Drupal CMS steps are clashing.

The istructions given in that page are correct. The commands to run are correct in that order.

mkdir my-drupal-site && cd my-drupal-site
ddev config --project-type=drupal11 --docroot=web
ddev start
ddev composer create drupal/cms

In your case, the directory is drupal-cms2, so the commands are the following.

mkdir drupal-cms2 && cd drupal-cms2
ddev config --project-type=drupal11 --docroot=web
ddev start
ddev composer create drupal/cms

Since Composer is used to create the project, ddev config --project-type=drupal11 --docroot=web and ddev start must be executed before ddev start and ddev composer create drupal/cms.

The error just says there is a .DS_Store file which should not be there. That is a hidden file Finder creates when showing a directory. If you run the commands I listed from the terminal, and created the directory ex-novo, there should not be any .DS_Store file.
