+# Pug-Assets
+
+Manage your assets and third-party transpiler (less, stylus, coffee, babel, etc.) and allow you to concat and/or minify them in production environment.
+
+## Install
+In the root directory of your Symfony project, open a terminal and enter:
+```shell
+composer require pug-php/pug-assets
+```
+
+Enable the plugin:
+```php
+use Pug\Pug;
+
+$pug = new Pug();
+
+// The facade syntax:
+Assets::enable($pug);
+$pug->render('... minify ...'); // here you can use minfiy, assets or concat keywords to wrap your assets
+
+Assets::disable($pug);
+$pug->render('... minify ...'); // here minfiy, assets or concat are simple tags again
+
+// Of the instanciation syntax:
+$assets = new Assets($pug);
+$pug->render('... minify ...'); // here you can use minfiy, assets or concat keywords to wrap your assets
+
+unset($assets);
+$pug->render('... minify ...'); // here minfiy, assets or concat are simple tags again
+```
+For more information about the concat/minify usage, see https://github.com/pug-php/pug-minify#readme
