+# Extra components
+
+This directory contains extra (optional) components to lvgl. 
+It's a good place for contributions as there are less strict expectations about the completeness and flexibility of the components here.
+
+In other words, if you have created a complex widget from other widgets, or modified an existing widget with special events, styles or animations, or have a new feature that could work as a plugin to lvgl feel free to the share it here.
