+## NVIDIA Container Toolkit
+
+[Source](https://docs.nvidia.com/datacenter/cloud-native/container-toolkit/latest/install-guide.html)
+
+### Installing with Apt
+
+```bash
+curl -fsSL https://nvidia.github.io/libnvidia-container/gpgkey | sudo gpg --dearmor -o /usr/share/keyrings/nvidia-container-toolkit-keyring.gpg \
+  && curl -s -L https://nvidia.github.io/libnvidia-container/stable/deb/nvidia-container-toolkit.list | \
+    sed 's#deb https://#deb [signed-by=/usr/share/keyrings/nvidia-container-toolkit-keyring.gpg] https://#g' | \
+    sudo tee /etc/apt/sources.list.d/nvidia-container-toolkit.list
+```
+
+```bash
+sudo apt-get update
+```
+
+```bash
+sudo apt-get install -y nvidia-container-toolkit
+```
+
+#### Configuration
+
+##### Prerequisites
+
+- You installed a supported container engine (Docker, Containerd, CRI-O, Podman).
+- You installed the NVIDIA Container Toolkit.
+
+```bash
+sudo nvidia-ctk runtime configure --runtime=docker --cdi.enabled
+```
+
+```bash
+sudo systemctl restart docker
+```
+
+### Sample Workload
+
+After you install and configure the toolkit and install an NVIDIA GPU Driver, you can verify your installation by running a sample workload.
+
+```bash
+sudo docker run --rm --runtime=nvidia --gpus all ubuntu nvidia-smi
+```
+
+Expected output:
+
+```console

+## Support for Container Device Interface(CDI)
+
+[Source](https://docs.nvidia.com/datacenter/cloud-native/container-toolkit/latest/cdi-support.html)
+
+### Prerequisites
+
+- You installed either the NVIDIA Container Toolkit or you installed the `nvidia-container-toolkit-base` package.
+  The base package includes the container runtime and the `nvidia-ctk` command-line interface, but avoids installing the container runtime hook and transitive dependencies.
+  The hook and dependencies are not needed on machines that use CDI exclusively
+- You installed an NVIDIA GPU Driver.
+
+Two common locations for CDI specifications are `/etc/cdi/` and `/var/run/cdi/`. The contents of the `/var/run/cdi/` directory are cleared on boot.
+
+1. Generate the CDI specification file:
+
+   ```bash
+   sudo nvidia-ctk cdi generate --output=/etc/cdi/nvidia.yaml
+   ```
+
+   Example output
+
+   ```console
+   INFO[0000] Auto-detected mode as "nvml"
+   INFO[0000] Selecting /dev/nvidia0 as /dev/nvidia0
+   INFO[0000] Selecting /dev/dri/card1 as /dev/dri/card1
+   INFO[0000] Selecting /dev/dri/renderD128 as /dev/dri/renderD128
+   INFO[0000] Using driver version xxx.xxx.xx
+    ...
+   ```
+
+2. (Optional) Check the names of the generated devices:
+
+   ```bash
+   nvidia-ctk cdi list
+   ```
+
+   Output
+
+   ```console
+   INFO[0000] Found 9 CDI devices
+   nvidia.com/gpu=all
+   nvidia.com/gpu=0
+   ```
+
+### Sample Workload
+
+```bash
+docker run --rm -ti --runtime=nvidia \
+    -e NVIDIA_VISIBLE_DEVICES=nvidia.com/gpu=all \
+      ubuntu nvidia-smi -L
+```
+
+Output
+
+```console
+GPU 0: NVIDIA GeForce RTX 3080 Laptop GPU (UUID: GPU-17c2b9a6-6be2-3857-f8e0-88143e2e621b)
+```
+
+## Technologies
+
+* Ubuntu 22.04.1 amd64
+* Docker Compose version v2.29.7
+* Python 3.10.12
+* pip 22.0.2
+* NVIDIA Container Toolkit CLI version 1.16.2
+* NVIDIA Driver 550.120
+* CUDA Version 12.4
+
+## How to Run
+
+Ensure variables in the `.env` file are correct.
+
+Install the required libraries in the python script.
+
+```bash
+pip install -r requirements.txt
+```
+
+### First Terminal
+
+1. Start the user interface with the following command.
+
+```bash
+docker compose --profile ui up
+```
+
+2.  Click `Launch Gazebo` on the menu.
+
+Simulated world and the drone model should be up and running in a Gazebo instance.
+
+### Second Terminal
+
+This will launch ardupilot, mavproxy and mavros services, and will scale up by the `SIM_DRONE_COUNT` env variable.
+
+1. Start the docker services with the following python script.
+
+```bash
+python3 sim_drone.py
+```
+
+### QGroundControl
+
+Simulated vehicle(s) should be connected to QGroundControl. `SIM_DRONE_COUNT` value should match the detected vehicle count on GCS.
+
+## Simulation Environment Variables
+
+`DRONE_SYS_ID` and `INSTANCE` environment variables are incremented by 1 for each additional simulated vehicle. `SERIAL0_PORT`, `SITL_PORT`, `MAVROS2_PORT`, `MAVROS1_PORT`,`FDM_PORT_IN` and `GSTREAMER_UDP_PORT` are incremented by 10. Without in-depth knowledge, changing the default value for these ports are not recommended.

+
+|      Variable      | Value |
+| :----------------: | :---: |
+|    DRONE_SYS_ID    |   1   |
+|      INSTANCE      |   0   |

+|    MAVROS1_PORT    | 14561 |
+|    FDM_PORT_IN     | 9002  |
+| GSTREAMER_UDP_PORT | 5600  |
+
+Second Vehicle,
+
+|      Variable      | Value |
+| :----------------: | :---: |
+|    DRONE_SYS_ID    |   2   |
+|      INSTANCE      |   1   |

+|    FDM_PORT_IN     | 9012  |
+| GSTREAMER_UDP_PORT | 5610  |
+
+Video stream would be available on UDP port on 5610 for the second vehicle after enabling streaming.
