-=======
-There isn't any practical difference between formats. In fact, Symfony
-transforms and caches all of them into PHP before running the application, so
-there's not even any performance difference between them.

-YAML is used by default when installing packages because it's concise and very
-readable. These are the main advantages and disadvantages of each format:
-
-* **YAML**: simple, clean and readable, but not all IDEs support autocompletion
-  and validation for it. :ref:`Learn the YAML syntax <yaml-format>`;
-* **XML**: autocompleted/validated by most IDEs and is parsed natively by PHP,
-  but sometimes it generates configuration considered too verbose. `Learn the XML syntax`_;
-* **PHP**: very powerful and it allows you to create dynamic configuration with
-  arrays or a :ref:`ConfigBuilder <config-config-builder>`.
