+# How to integrate your vehicle in AWSIM environment
+
+## Overview
+
+[AWSIM](https://github.com/tier4/AWSIM) is an open-source simulator designed by TIER IV for
+training and evaluating autonomous driving systems.
+It provides a realistic virtual environment for simulating various real-world scenarios, enabling
+users to test and refine their autonomous systems before deployment on actual vehicles.
+
+## Setup Unity Project
+
+To add your environment and vehicle to the AWSIM simulation,
+you need to set up the [Unity](https://unity.com/) environment on your computer.
+Please follow the steps on the [`Setup Unity Project`](https://tier4.github.io/AWSIM/GettingStarted/SetupUnityProject/)
+documentation page
+to set up the Unity environment on your computer.

+
+## New Vehicle Integration
+
+To incorporate your vehicle into the AWSIM environment,
+you'll need a 3D model file (.dae, .fbx) of your vehicle.
+Please refer to the steps on the [`Add New Vehicle
+documentation page`](https://tier4.github.io/AWSIM/Components/Vehicle/AddNewVehicle/AddAVehicle/) to add your own vehicle to the AWSIM
+project environment. During these steps, you'll configure
+your sensor URDF design on your vehicle.
+Our tutorial vehicle is shown in the AWSIM environment in the following image.

+
+## Environment Integration
+
+Creating custom 3D environments for AWSIM is feasible,
+but it's recommended to adhere to the .fbx file format.
+Materials and textures should be stored in separate directories
+for seamless integration with Unity. This format facilitates material
+importation and replacement during import.
+Please refer to the steps on the
+[`Add Environment documentation page`](https://tier4.github.io/AWSIM/Components/Environment/AddNewEnvironment/AddEnvironment/)
+to add your custom environment to the AWSIM project environment.

+
+## Others
+
+Additionally, you can incorporate traffic and NPCs,
+generate point cloud maps using lanelet2 maps, and
+perform other tasks by following the relevant
+documentation steps provided in the [`AWSIM documentation`](https://tier4.github.io/AWSIM/).
