Using the UI Installer on Gitpod

Test Project Browser via Gitpod from the [Try It Now] Gitpod button on the Project Browser project page.

After it's up and running, execute the following in the terminal for enhanced security or just skip it:

ddev composer require drupal/core-vendor-hardening

There is no need to require the drupal/automatic_updates or drupal/project_browser dev packages (or clone repositories for these modules), as the dev packages are already required in the pod. 

Then go to the Project Browser's main page - Admin > Extend > Browse modules. Now, you can click "Add and Install" for modules that are not on yet installed. (Login: admin/admin)

If for some reason, the Browse modules menu item doesn't exist:

• Go to Admin > Extend and enable the "Package manager" and "Project Browser" modules.
• Go to Admin > Configuration > Development > Project Browser and check the box 'Allow installing via UI (experimental)' and hit Save at the bottom.
