 ```
 
+Some extensions require additional dependencies (for example `imagick`).
+By default, `Install-PhpExtension` automatically installs these dependencies in the directory where PHP is installed.
+If you want to install them in another directory, you have to call the `Install-PhpExtensionPrerequisite` command, and specify the `-NoDependncies` option for `Install-PhpExtension`.
+
 PS: `Install-PhpExtension` can also be used to upgrade (or downgrade) a PHP extension to the most recent version available online.
