+## Lead teleop
+
+[lead_teleop.launch](./jsk_unitree_startup/launch/lead_teleop.launch) is designed to interface with a mechanical button and an LED,
+publishing joystick messages (`joy_msg`) to ROS using the rosserial library.
+The node captures button presses and publishes the count of presses as part of the `/joy` messages to ROS.
+
+### Hardware Setup
+
+- Joystick: Interprets analog signals from two axes.
+- LEDs: One Adafruit NeoPixel strip for status indication.
+- Button: A single mechanical button used to trigger different commands based on the number of presses.
+
+For detailed instructions on setting up the Arduino IDE, see [Setup Arduino IDE for LeadJoyDevelopment](#setup-arduino-ide-for-leadjoydevelopment).

 ### Setup Arduino IDE for LeadJoyDevelopment
 - Add Seeduino XIAO to board manager
     - Open arduino IDE. `~/arduino-$ARDUINO_VERSION/arduino`

+### ROS Parameters
+
+- `~deadzone`: Adjusts the sensitivity of the joystick's zero point.
+- `~press_interval`: Time window to register multiple button presses as a single action.
+- `~debounce_period`: Debounce time to stabilize the button input.
+
+### Visual Feedback
+
+The Mechanical keyboard LED button changes colors based on the button pressed to provide immediate visual feedback. Each button press is associated with a different color.

+| 4 presses      | White | Disable movement           | Unitree stops moving.                 |
+| 5 presses      | Purple | Enable movement           | Unitree is able to move again.        |
+
+The robot's motion and action mappings, such as stopping, moving, sitting, and standing, are defined in [rosserial_node.launch](./jsk_unitree_startup/launch/rosserial_node.launch) and [lead_joystick_teleop.yaml](./jsk_unitree_startup/config/lead_joystick_teleop.yaml). These files control the robot's responses to joystick inputs and can be customized as needed.
