+# Integration of the Input System Package with ML-Agents
+
+## Overview
+One area we are always trying to improve is getting developers up and running with ML-Agents.  With this in mind,
+we have implemented an `InputActuatorComponent` that sets up an action space for your `Agent` based on
+an `InputActionAsset` that is referenced by the `IInputActionAssetProvider` interface, or the `PlayerInput` component
+that may be living on your player controlled `Agent`.  This means that if you have code outside of your agent that
+handles input, you will not need to implement the Heuristic function in agent as well.  The `InputActuatorComponent`
+will handle this for you.  You can now train and run inference on `Agents` with an action space defined by an `InputActionAsset`.
+
+This implementation includes:
+
+* C# `InputActuatorComponent` you can attach to your Agent.
+* Implement the `IInputActionAssetProvider` in the `Componenet` where you handle player input.
+* An example environment where the input handling code is not in the Heuristic function of the Agent subclass.
+
+### Feedback
+We have only implemented a small subset of `InputControl` types that we thought would cover a large portion of what
+most developers would use.  Please let us know if you want more control types implemented by posting in the [ML-Agents
+forum.](https://forum.unity.com/forums/ml-agents.453/)
+
+We would also like your feedback on the workflow of integrating this into your games.  If you run
+into workflow issues please let us know in the ML-Agents forums, or if you've discovered a bug,
+please file a bug on our GitHub page.
+
+## Getting started
+The C# code for the `InputActuatorComponent` exists inside of the extensions package (com.unity.ml-agents.extensions).  A good first step would be to familiarize with the extensions package by reading the document [here](com.unity.ml-agents.extensions.md).  The second step would be to take a look at how we have implemented the C# code in the example Input Integration scene (located under  ML-Agents-Input-Example/Assets/ML-Agents/Examples/PushBlock/).  Once you have some familiarity, then the next step would be to add the InputActuatorComponent to your player Agent.  The example we have implemented uses C# Events to send information from the Input System.
+
+Additionally, see below for additional technical specifications on the C# code for the InputActuatorComponent.
+
+## Technical specifications for the InputActuatorComponent
+
+### `IInputActionsAssetProvider` Interface
+The `InputActuatorComponent` searches for a `Component` that implements
+`IInputActionAssetProvider` on the `GameObject` they both are attached to.  It is important to note
+that if multiple `Components` on your `GameObject` need to access an `InputActionAsset` to handle events,
+they will need to share the same instance of the `InputActionAsset` that is returned from the
+`IInputActionAssetProvider`.
+
+### `InputActuatorComponent` class
+The `InputActuatorComponent` is the bridge between ML-Agents and the Input System.. It allows ML-Agents to
+* create an `ActionSpec` for your Agent based on an `InputActionAsset` that comes from an
+`IInputActionAssetProvider`.
+* send simulated input from a training process or a neural network
+* let developers keep their input handling code in one place
+
+This is accomplished by adding the `InputActuatorComponenet` to an Agent which already has the PlayerInput component attached.
+
+### Setting up a scene using the `InputActuatorComponent`
+1. Add the `com.unity.inputsystem` version 1.1.0-preview.3 or later to your project via the Package Manager window.
+2. If you have already setup an InputActionAsset skip to Step 3, otherwise follow these sub steps:
+    1. Create an InputActionAsset to allow your Agent to be controlled by the Input System.
+    2. Handle the events from the Input System where you normally would (i.e. a script external to your Agent class).
+3. Add the InputSystemActuatorComponent to the GameObject that has the `PlayerInput` and `Agent` components attached.
