+### Parameters in messages
+
+Sometimes it is convenient to include a dynamic parameter in the translation - as seen in the Latte examples above.
+
+Neon:
+
+``` yaml
+user.name.taken: "Sorry, the username %name% is already taken, please try a different one."
+```
+
+Latte:
+
+``` smarty
+{_user.name.taken, [name => "Ales"]}
+```
+
+Presenter/Model:
+
+``` php
+$this->translator->translate('user.name.taken', [name => 'Ales']);
+```
+
+**Note**: When passing parameters to the translator, the parameter names must not be enclosed in `%` characters. This is done by `Contributte/Translation` automatically.
+
 ## Loaders
 
 By default the extension will look for `.neon` files.
