+## Roadmap 
+
+This repository is under heavy development. Refer to the [project kanban board](https://github.com/users/Philzen/projects/2/views/2) 
+for ongoing updates on the road to feature completeness. Should you notice a blind spot 
+regarding TestNG features that should be included in a project migration, or if you have idea 
+for a particular implementation, your contributions are welcome!
+
+See below tables for a quick overview of the implementation progress.
