+## Overview
 Robot sensor packages available on Unity.
 You can communicate sensor info via ROS and ROS2 using ROSTCPConnector and ROSTCPEndpoint.  
 
 The following sensors are added.
 
-- 3D LiDAR (Velodyne VLP-16)
-- 2D LiDAR (Hokuyo UST-30LX)
-- RGB Camera (Logitech C910)
+- Velodyne 3D LiDAR (Velodyne VLP-16, VLP-16-HiRes, VLP-32)
+- Livox 3D LiDAR(Avia, Horizon, Mid40, Mid70, Tele)
+- RGB Camera
+- RGBD Camera
 - IMU
+- GNSS
+- (GroundTruth)
+- (TF)
 
 There are several Prefab and Scene files available for testing each sensor.
-Check [this directory](https://github.com/Field-Robotics-Japan/sensors_unity/tree/develop/Assets/Scenes).
-
-# How to use (ROS)
-## 1. Launch ROS packages
-### 1-1 ros_tcp_endpoint
-Launch the `ros_tcp_endpoint` with following command.
-```bash
-roslaunch ros_tcp_endpoint endpoint.launch 
-```
-
-### 1-2 Sensors
-#### 1-2-1 velodyne_pointcloud
-Launch the `velodyne_pointcloud` package with following launch file.  
-Please create launch file by copy and paste following script.  
-**The version of `velodyne_pointcloud` package should be later than 1.6.0.**  
-If you fail to lanch following launch file, please download velodyne package directoly into your workspace, build it, and launch them again.  
-https://github.com/ros-drivers/velodyne
-```xml
-<launch>
-  <arg name="calibration" default="$(find velodyne_pointcloud)/params/VLP16db.yaml" />
-  <arg name="manager" default="velodyne_pointcloud" />
-  <arg name="max_range" default="100.0" />
-  <arg name="min_range" default="0.1" />
-  <arg name="frame_id" default="velodyne" />
-
-  <node pkg="velodyne_pointcloud" type="transform_node" name="$(arg manager)">
-    <param name="model" value="VLP16"/>
-    <param name="calibration" value="$(arg calibration)"/>
-    <param name="max_range" value="$(arg max_range)"/>
-    <param name="min_range" value="$(arg min_range)"/>
-    <param name="frame_id" value="$(arg frame_id)"/>
-    <!-- <param name="view_direction" value="0"/> -->
-    <!-- <param name="view_width" value="360"/> -->
-  </node>
-</launch>
-```
-
-#### 1-2-2 RGB Camera
-Image communication between Unity and ROS is done using JPEG compression.  
-You can set the topic name in the Unity inspector window.  
-
-**Note** :  
-Message type is sensor_msgs/CompressedImage.
-So, the topic name must end with "/compressed".
 
-In order to handle sensor_msgs/CompressedImage,  
-launch the `image_transport` package with following launch file.  
-Please create launch file by copy and paste following script.
-
-```xml
-<launch>
-    <node name="image_republish" pkg="image_transport" 
-          type="republish" args="compressed raw">
-      <remap from="input" to="/image_raw/compressed" />
-      <remap from="output" to="/image_exp" />
-    </node>
-</launch>
-```
-If you want to check the images in Rviz, you don't need to use the above launch file.

-#### 1-2-3 IMU
-It can be used in the same way as a normal IMU sensor.
+## Package Installation (For using UnitySensors in your project)
+1. Using Unity 2021.3 or later, open the Package Manager from `Window` -> `Package Manager`.
+2. In the Package Manager window, find and click the + button in the upper lefthand corner of the window. Select `Add package from git URL....`
 
-## 2. Clone and run on Unity
-1. Just to clone this repo with `git clone --recursive https://github.com/Field-Robotics-Japan/UnitySensorsROSAssets.git` command.
-1. Then, open the project file with UnityHub.
-1. Finally, run the scene file for the sensor you want to test.
+3. Enter the git URL for the desired package. 
+    1. For the UnitySensors, enter `https://github.com/Field-Robotics-Japan/UnitySensors.git?path=/Assets/UnitySensors#v1.0b`.
+    2. For the UnitySensorsROS, enter `https://github.com/Field-Robotics-Japan/UnitySensorsROS.git?path=/Assets/UnitySensorsROS#v1.0b`.
+    __Note: UnitySensorsROS does not contain UnitySensors.__
+4. Click `Add`.
 
-You can try all the sensors in the "`Sensors`" scene file.
