+# Isaac ROS Occupancy Grid Localizer Nav2 Isaac Sim Tutorial
+
+<div align="center"><img alt="Isaac ROS  Occupancy Grid Localizer Expected Output" src="../resources/nav2_isaac_sim.png" width="600px"/></div>
+
+## Overview
+
+This tutorial describes how to integrate the Isaac ROS Occupancy Grid Localizer with a simulated robot running in Isaac Sim with Nav2.
+
+Last validated with [Isaac Sim 2022.1.0](https://docs.omniverse.nvidia.com/app_isaacsim/app_isaacsim/release_notes.html#id10).
+
+## Tutorial Walkthrough
+
+1. Complete the [Quickstart section](../README.md#quickstart) in the main README.
+2. Launch the Docker container using the `run_dev.sh` script:
+
+    ```bash
+    cd ~/workspaces/isaac_ros-dev/src/isaac_ros_common && \
+      ./scripts/run_dev.sh
+    ```
+
+3. Inside the container, build and source the workspace:  
+
+    ```bash
+    cd /workspaces/isaac_ros-dev && \
+      colcon build --symlink-install && \
+      source install/setup.bash
+    ```
+
+4. Install and launch Isaac Sim following the steps in the [Isaac ROS Isaac Sim Setup Guide](https://github.com/NVIDIA-ISAAC-ROS/isaac_ros_common/blob/main/docs/isaac-sim-sil-setup.md)
+5. Open up the Isaac ROS Common USD scene (using the *Content* tab) located at:
+
+    ```text
+    http://omniverse-content-production.s3-us-west-2.amazonaws.com/Assets/Isaac/2022.2.1/Isaac/Samples/ROS2/Scenario/carter_warehouse_apriltags_worker.usd
+    ```
+   And wait for it to load completely.
+6. Press **Play** to start publishing data from the Isaac Sim application.
+
+7. Run the launch file and you should see a nav2 window pop up.
+
+    ```bash
+    ros2 launch isaac_ros_occupancy_grid_localizer isaac_ros_occupancy_grid_localizer_nav2.launch.py
+    ```
+
+8. Open a new terminal using the `run_dev.sh` script:
+
+    ```bash
+    cd ~/workspaces/isaac_ros-dev/src/isaac_ros_common && \
+      ./scripts/run_dev.sh
+    ```
+
+9. Trigger the localization service using the command line interface:
+
+    ```bash
+    ros2 service call /trigger_grid_search_localization std_srvs/srv/Empty {}
+    ```
+
+10. You should see the laser scan in rviz. This happens when the transform between map and carter_lidar frame is available. The robot is now localized. You can give a position setpoint using the `2D Nav Goal` button as shown below. You can relocalize again at any point by running the `ros2 service call` command above.
