Full documentation can be found at the [official website](https://www.fast-downward.org/). The executable can be found at `/courses/TDDE05/software/downward/builds/release/bin`.
+* unified planning: the Unified-Planning library makes it easy to formulate planning problems and to invoke automated planners. More information and tutorials can be found in the [official documentation](https://unified-planning.readthedocs.io/en/latest/).
 * ROS2 Planning System: a more advanced planning system for ros2. Documentation can be found at the official page [plansys2](https://plansys2.github.io/) and through the examples on [github](https://github.com/PlanSys2/ros2_planning_system_examples).
