 Technical Requirements
 ----------------------
 
 Before creating your first Symfony application you must:
 
-* Make sure to have PHP 7.1 or higher installed (and :doc:`these PHP extensions </reference/requirements>`
-  which are installed and enabled by default by PHP);
+* Install PHP 7.1 or higher and these PHP extensions (which are installed and
+  enabled by default in most PHP 7 installations): `Ctype`_, `iconv`_, `JSON`_,
+  `PCRE`_, `Session`_, `SimpleXML`_, and `Tokenizer`_;
 * `Install Composer`_, which is used to install PHP packages;
 * `Install Symfony`_, which creates in your computer a binary called ``symfony``
   that provides all the tools you need to develop your application locally.
 
+The ``symfony`` binary provides a tool to check if your computer meets these
+requirements. Open your console terminal and run this command:
