+Welcome to Pyrate!
+==================
+
+This project offers algorithms targeted towards autonomous surface vehicles implemented in the Python 3.6+ programming language.
+The functionality included in the Pyrate Python package enables the perception and processing of environmental features, planning of strategies and trajectories as well as action taking.
+Pyrate is therefore divided into multiple distinct subpackages *sense*, *plan* and *act*, as well as the *common* package for additional features such as file I/O and mathematical abstractions.
+
+The sense subpackage includes algorithms for computer vision, single and multi target state estimation, data smoothing and more.
+In the plan subpackage, the perceived state of the agent and its environment is processed to compute trajectories for long- and short-term navigation as well as strategic decisions.
+This also includes methods for gradient based and gradient free optimization methods are included.
+Finally, the act subpackage contains state controllers to carry out planned behavior.

+
+This project aims at providing the algorithmic backend for the ROS driven on-board systems and simulations.
+Models of the robot's mechanics, electronics and its environment shall be developed within their own respective repository.
+Furthermore technical specifications, maps and so on go into a separate project repository as well.
+This ensures a clean separation of distinct requirements for quality assurance and responsibilities that distinguish these projects.
