+# ROS Support for jupyter notebooks
+
+While the Jupyter ecosystem has been widely adopted by
+the Data Science and Machine Learning community, the 
+robotics community has not jumped on the band wagon yet! 
+Most tools around ROS, the Robot Operating System, are 
+built using Python and QT.
+
+However, using QT seperates the user away from the code.
+We've built an initial version of the ROS tools for jupyter
+notebook, trying to promote a rich, interactive experience
+for Robotics developers utilizing the power of the jupyter 
+notebook.
+
+With jupyter-ros, it's possible to easily create widgets for 
+custom message types to send messages. 
+
+In the future, we plan to bring simple and fast real-time
+plotting from ROS topics to this library.
+
+If you find this initial package useful, don't hesitate to 
+contribute!
+You can also always reach out to w.vollprecht@gmail.com or
