+## 1. Introduction
+The WAGO 750-402 Display Example is a minimal demonstation showing how to display the digital inputs on a WAGO 750-402 EtherCAT terminal using the QiTechmachine framework.
+It represents the simplest possible hardware interaction in the system:
+Displayung the LED Inputs using the QiTech Control Dashboard.

 ### 3.2.2 Wiring Steps (Used in This Example)
+
+We supply power to the other devices by using the **750-602 EtherCAT Power Terminal**
+
+Perform the following wireing on the Ethernet-Switch:
+
+1. Red wire (+24V) → PWR+
+2. Black wire (0V) → RPS-

+Next We need to Wire the EtherCat E-Bus
+
+Perform the next wireing Steps:
+
+1. Green wire (Ground) → **Terminal4**
+2. Red wire (+24V) from  **750-602 EtherCAT Power Terminal** → **Terminal 2**
+3. Black wire(0V) from **750-602 EtherCAT Power Terminal** → **Terminal 3**
+4. Red wire (+24V) from **750-354 EtherCAT Coupler** → **Terminal 6**
+5. Yellow wire (0V) from **750-354 EtherCAT Coupler** → **Terminal 7**

+### Power
+
+Connect the 2787-2144 EtherCAT to the power outlet
+
+### Ehternet
+
+Use a standard LAN cable to your PC → **852-1322 Ethernet-Switch** 
+
+And another from **852-1322 Ethernet-Switch** → **750-354 EtherCAT Coupler**

 ## 4. Software Setup

 ### 4.1 Installing on Ubuntu/Debian
+Paste this into your terminal:

+```bash
+# Press Enter when prompted
+curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
+
+sudo apt update
+sudo apt install -y npm nodejs git
+
+git clone git@github.com:qitechgmbh/control.git
+cd control/electron
+npm install
+```
 ### 4.2 Running the Backend
+```bash
+./cargo_run_linux.sh
+```
+This script:
+
+- Builds the backend
+
+- Grants required system capabilities (raw sockets)
+
+- Starts EtherCAT communication
+
+Ensure the WAGO750-402 is connected.

 ### 4.3 Running the Frontend
+```bash
+cd electron
+npm run start
+```
+
+This launches the QiTech Control dashboard.
