-<!-- XXX Need to improve this introduction -->
+Wekan is an open-source and collaborative kanban board application.
 
-Wekan is an open-source *kanban* board that let you organize things in cards,
-and cards in lists. You can use it alone, or with your team and family thanks to
-our real-time synchronisation feature. Wekan is a land of liberty and you can
-implement all sort of workflows on it using tags, comments, member assignation,
-and many more.
+Whether you’re maintaining a personal todo list, planning your holidays with
+some friends, or working in a team on your next revolutionary idea, Kanban
+boards are an unbeatable tool to keep your things organized. They give you a
+visual overview of the current state of your project, and make you productive by
+allowing you to focus on the few items that matter the most.
