- Created a new document for the Station interface, detailing its menu structure, process data, safety functions, frames, and smartPAD function buttons.
- Added a document for RobotPowerControl, explaining its purpose for safely shutting down or restarting the KUKA Sunrise Cabinet controller.
- Introduced ServerFriRos2 documentation, outlining its role in establishing an FRI connection between the KUKA LBR iiwa and a ROS 2 computer.
- Documented the TeachKuka application, which allows manual teaching of the KUKA LBR iiwa, including position capturing and trajectory recording.
- Added an overview of Sunrise Workbench, including installation instructions for Windows and Linux.
- Created a section on installing a Windows compatibility tool (PortProton) on Linux.
- Documented the installation process for SunriseWorkbench on Linux using PortProton.
- Added installation instructions for SunriseWorkbench on Windows.
- Created troubleshooting documentation for configuration errors and SSL errors during installation.

+# Getting started
+
+This section explains how to prepare the environment, connect to the controller, install the project, and start controlling the robot.
+
+## Quick start
+
+1. [**Sunrise Workbench setup**](sunrise-setup.md) — prepare the KUKA controller, upload `ServerFriRos2`, and configure the network. *(Physical robot only.)*
+2. [**Connect to the server**](remote-access.md) — choose local or remote deployment and connect to the control server over SSH.
+3. [**Install the project**](installation.md) — install LWC using `curl`, `git`, or manually.
+4. [**Configure the system**](configuration.md) — configure `cobot-setting.yaml` with the robot IP, ports, and tools.
+5. [**cobot CLI**](cli-reference.md) — learn the commands for running, building, and updating the project.
+
+!!! tip "Simulation only?"
+    Skip the physical-controller setup and run `cobot run --simulate` after installation.
