-            Here are some useful Composer commands to get you started:
-
-            * `composer install`: Install dependencies.
-            * `composer test`: Run the full test suite.
-            * `composer phpcs`: Check for code style violations.
-            * `composer phpcbf`: Automatically fix code style violations.
-            * `composer phpunit`: Run unit tests.
-            * `composer behat`: Run behavior-driven tests.
-
-            To run a single Behat test, you can use the following command:
-
-            ```bash
-            # Run all tests in a single file
-            composer behat features/some-feature.feature
-
-            # Run only a specific scenario (where 123 is the line number of the "Scenario:" title)
-            composer behat features/some-feature.feature:123
-            ```
