 Integrated Composer simplifies dependency management by extending Composer functionality to core WordPress and Drupal files, treating them as a managed dependency. Instead of committing your vendor directory with your dependencies, you simply commit your `composer.json` and `composer.lock` file to your Pantheon site, and we automate the rest. This enables one-click updates from the Pantheon Dashboard for upstream updates and Composer dependencies on your site, streamlining site maintenance and saving significant time and effort.

Use commas or a line break to separate excluded elements. This can be useful to prevent landing pages with animation or videos from causing false positive Visual Regression Tests:
