+## Running Tests on Another Machine
+
+To run tests on a target connected to another machine (e.g., in a GitLab CI pipeline), follow these steps:
+
+### On the Host Machine
+
+Set up a J-Link tunnel to make the target accessible from anywhere:
+
+```shell
+JLinkRemoteServerCL -UseTunnel -TunnelBySN
+```
+
+The terminal output should look like this:
+
+```
+2025-06-04 08:43:57 - Remote Server started
+2025-06-04 08:43:57 - Connected to J-Link with S/N 801000372
+2025-06-04 08:43:57 - Resolving tunnel server name (jlink-europe.segger.com)...
+2025-06-04 08:43:57 - Tunnel server IP: 185.162.249.2
+2025-06-04 08:43:57 - Registered at tunnel server
+2025-06-04 08:43:57 - Waiting for client connection
+```
+
+`801000372` is the tunnel ID required to reach the target. Include it in your CMake command:
+
+```shell
+cmake --preset Test -DTUNNEL_ID=801000372
+```
+
+When you run the tests, they will automatically execute on the host machine.

 # TSM_PicoW_Sensor
-This project uses the PicoW board to publish sensor values (humidity and temperature) to an MQTT broker.
+
+This project utilizes the Raspberry Pi Pico W board to measure data (humidity and temperature) and publish these values to an MQTT broker. 
+
+## Project Overview
+
+The TSM_PicoW_Sensor firmware collects sensor data and publishes it to an MQTT broker over Wi-Fi. The configuration is flexible and can be updated at runtime using a serial terminal. The project supports automated testing, including remote execution via a J-Link tunnel.
+
+---
+
+## CI/CD
+
+> **Note:** The automated test job in the CI pipeline is currently commented out because a Pico W board is not always available. To enable automated testing, uncomment the test job in the CI configuration and ensure a J-Link tunnel is set up as described below.
+
+---
 
 ## Target Configuration
 
-Use a serial terminal (baud rate: 115200) to configure the board by sending commands. The application stores the parameters in flash memory. You must restart the device to apply any changes.
+The device parameters (Wi-Fi credentials, MQTT broker, topics, etc.) are stored in flash memory and can be configured via a serial terminal (baud rate: **115200**). After updating any parameter, restart the device to apply changes.
 
-### Wi-Fi
+### Wi-Fi Setup
+
+Set the Wi-Fi SSID and password using the following commands:
 
 ```shell
 McuMinINI write settings.ini WiFi ssid "YOUR_SSID"
 McuMinINI write settings.ini WiFi pass "YOUR_PASSWORD"
 ```
 
-### MQTT
+### MQTT Setup
+
+Configure the MQTT broker and authentication:
 
-Broker information:
 ```shell
 McuMinINI write settings.ini MQTT broker "BROKER_NAME"
 McuMinINI write settings.ini MQTT user "USERNAME"
 McuMinINI write settings.ini MQTT pass "PASSWORD"
 ```
 
-Topic names:
+Set the MQTT topic names:
+
 ```shell
 McuMinINI write settings.ini MQTT topic_sensor_update "<user>/<room>/<device>/update"
 McuMinINI write settings.ini MQTT topic_send_measurement "<user>/<room>/<device>/cmd/measure"
 ```
 
-## Build
-Project has `Debug`, `Release` and `Test` targets, using CMake Presets. 
+---
+
+## Build Instructions
+
+The project uses CMake presets for different build configurations: **Debug**, **Release**, and **Test**.
+
+### Configure the Project
+
+Here are the avalaible cmake presets:
 
-**Configure:**
 ```shell
-cmake --list-presets
-cmake --preset Debug
-cmake --preset Release
-cmake --preset Test
+cmake --preset Debug      
+cmake --preset Release    
+cmake --preset Test       
 ```
 
-**Build:**
+### Build the Project
+
+Here are the build options:
+
 ```shell
-cmake --build --list-presets
 cmake --build --preset app-debug
 cmake --build --preset app-release
 cmake --build --preset app-test
 ```
 
-**Test:**
-```shell
-ctest --list-presets
-ctest --test-dir build/Test -R Led_1
-```
+## Running Tests
 
-**Workflow:**
-```shell
-cmake --workflow --list-presets
-```
+The project supports running tests both locally and remotely. Remote testing is useful for CI pipelines or when the hardware is not directly connected to your development machine.
 
-## Running Tests on Another Machine
+### Remote Test Execution

-`801000372` is the tunnel ID required to reach the target. Include it in your CMake command:
+The serial number (e.g., `801000372`) is your **tunnel ID**.
+
+#### 2. On the Development/CI Machine

+Configure CMake to use the tunnel ID:
