+Leistungsschutzrecht Addon
+==========================
+
+Main author Michael Vogel
+
+This addon handles legal problems with the German link tax, named "Leistungsschutzrecht" by shortening preview texts.
+Additionally it is possibly to suppress preview pictures completely to avoid any legal problems.
+
+## configuration
+
+If you want to suppress pictures in previews, add this to your global `config/addon.config.php`:
+
+	'leistungsschutzrecht' => [
+		'suppress_photos' => true,
+	],
+
