+# Hardware-In-The-Loop Simulation
+We configure a multi-machine HITL simulation, where a powerful desktop computer runs Isaac Simulator and rendering, and one/multiple jetson compute boards run robot-specific programs (planning, mapping, etc.).
+## Requirement
+A desktop computer configured according to [here](/docs/getting_started). One/multiple ORIN AGX/NX configured according to [here](/docs/real_world/installation/).
+
+## Communication
+All machines should connect to the same network. In our test, all machines are connected to the same router with ethernet cables. Ensure that all machines are able to `ping` others' IP addresses.
+
+### Run
+On the desktop computer, under your Airstack folder, run
+```
+docker compose up isaac-sim-hitl
+```
+You should see the isaac simulator being launched.
+On the Jetson computer, run
+```
+docker compose up robot_l4t
+```
+Once the scene is played in the Isaac simulator, the rviz GUI on the Jetson should start displaying sensor data, which means the connection is successful.

-# Installation on Hardware
+# Installation on ORIN AGX/NX
+
+We have tested installation and running robot container on Jetson ORIN AGX/NX and Ubuntu 22.04.
+
+## Setup
+Ensure you have docker installed.
+### Clone
+
+```
+git clone --recursive -j8 git@github.com:castacks/AirStack.git
+```
+Checkout to the correct branch:
+```
+git checkout jkeller/jetson_36.4
+```
+## Configure
+
+Run `./configure.sh` and follow the instructions in the prompts to do an initial configuration of the repo.
+
+Pull the correct image:
+```
+docker compose pull robot_l4t
+```
+
+## Run
+```
+docker compose up robot_l4t
+```
+You should be able to see the rviz GUI being launched.
