+### `n98-magerun2 dev:theme:active`
+
+Allows to get list of used themes. Example output (suitable for deploy static command):
+
+    --theme Swissup/argento-pure2
+
+This is useful for scripts to facilitate faster builds.
+
+Many Magento 2 themes come bundled with many actual themes, and deploying static assets takes huge time.
+All because you unnecessarily minify a ton of CSS and Javascript files for themes which are not even in use!
+
+You can deploy just the used themes with:
+
+    bin/magento setup:static-content:deploy --theme Magento/backend $(n98-magerun2 dev:theme:active)
