+  description: >-
+    Think of Vikunja like the notebook you have with all your things to keep track of.
+    But with superpowers.
+    Stay organized
+    Organize all of your tasks in projects. Create subprojects organize everything hierarchical and keep related stuff grouped together.
+
+
+    Collaborate with peers
+    Vikunja lets you easily share a project with another user or a whole team! Assignments show who's working on what.
+
+
+    Use it how you need it
+    You can view your tasks in the classic list view - or in a Gantt Chart, or Table view, or Kanban Board. Whatever you need!
+
+
+    Built for speed.
+    We built Vikunja with speed in mind - every interaction takes less than 100ms. No more loading spinners.
+    Because a productive tool should not get in your way.
+
+
+    Import your tasks from Todoist, Trello or Microsoft To-Do
+    Because work does not happen in one tool only.
