+## Title
+
+The Title component used to have some different css based on a specific `classModifier` or `className`. For `classModifier` it was called `bigTitle` and for `className` it was `af-subtitle`. This two custom css have now been deleted for the component. If you are using them on your project, you should remove them and make this implementation yourself.
+The Title component only implement what our UXs have designed.
