 # Description
 
-This ROS node contains the physical description of the model car used for the [ADC competition](http://autonomousdrivingchallenge.com/ "ADC competition").
-This description can be used in either the real model car and also in the simulated model.
+This ROS package contains the physical description of a 1:8 scale model car used for the autonomous driving competitions. This description can be used either in the real model car or in the simulated model.

 # How to use it
 
-Download the node inside a catkin workspace:
+* Move to workspace:
+```
+roscd && cd ../src
+```
 
- git clone https://gitlab.iri.upc.edu/seat_adc/model_car_description.git
+* Clone the repository: 
+```
+git clone https://gitlab.iri.upc.edu/labrobotica/ros/devices/dynamixel_pan_tilt/iri_dynamixel_pan_tilt_driver.git -b kinetic-migration
+```
 
-This node provides two launch files:
+* Compile:
+```
+roscd && cd .. && catkin_make -DCMAKE_BUILD_TYPE=Release
+```
 
+This package provides a simple launch file to display the physical description of the model car and control each of the joints using the [joint_state_publisher](http://wiki.ros.org/joint_state_publisher) node:
+```
+roslaunch model_car_description description_test.launch
+```
 
+This launch file include a second launch file named *description.launch* which is intended to be included from other launch file that require the model car description. This launch file has two parameters:
+
+* **name** (default=model_car): name of the car used as a namespace to include everything inside it.
+* **sim_config_path** (default=model_car_gazebo/config): path where the simulation sensor configuration files for all sensors are located. See the [model_car_gazebo]() documentation for more details.
+
+To include the model_car_description into an other launch file, include the following lines:
+```
+  <include file="$(find model_car_description)/launch/description.launch">
+    <arg name="name"  value="$(arg name)"/>
+    <arg name="sim_config_path" value="$(arg sim_config_path)"/>
+  </include>
+```
