 Simulation plays an important role in robotics development, and we’re here to ensure that roboticists can use Unity for these simulations. We're starting off with a set of tools to make it easier to use Unity with existing ROS-based workflows. Try out some of our samples below to get started quickly.
 
-## Getting Started with Unity Robotics
+## Getting Started
+### [Quick Installation Instructions](tutorials/quick_setup.md)
+
+Brief steps on installing the Unity Robotics packages.
+
+### [Pick-and-Place Demo](tutorials/pick_and_place/README.md)
+
+A complete end-to-end demonstration, including how to set up the Unity environment, how to import a robot from URDF, and how to set up two-way communication with ROS for control.
+
+### [**New!**] [Object Pose Estimation Demo](https://github.com/Unity-Technologies/Robotics-Object-Pose-Estimation)
+
+A complete end-to-end demonstration in which we collect training data in Unity and use that data to train a deep neural network to predict the pose of a cube. This model is then deployed in a simulated robotic pick-and-place task.
+
+### [Articulations Robot Demo](https://github.com/Unity-Technologies/articulations-robot-demo)
+
+A robot simulation demonstrating Unity's new physics solver (no ROS dependency).

 - **Force/Torque Sensor API**. This API will allow users to get the force and torque acting on an articulation body (useful for simulating a force/torque sensor!), as well as to get the motor torque applied by an articulation drive.
 - **Query primitives**. These simple, GameObject-less shapes allow for collision detection without requiring simulation (i.e., without calling Physics.Simulate). This feature will allow users to initialize objects in feasible locations, and can also be used for motion planning.
