+There are some :ref:`technical requirements for running Symfony applications <symfony-tech-requirements>`.
+In your development machine, the recommended way to check these requirements is
+to use `Symfony CLI`_. However, in your production server you might prefer to
+not install the Symfony CLI tool. In those cases, install this other package in
+your application:
+
+.. code-block:: terminal
+
+    $ composer require symfony/requirements-checker
+
+Then, make sure that the checker is included in your Composer scripts:
+
+.. code-block:: json
+
+    {
+        "...": "...",
+
+        "scripts": {
