 ## Preparation
 
+You can either download the archive by cloning the repository or using wget.
 
-1. Clone the repository:  
-```sh 
-git clone https://github.com/powerapi-ng/powerapi-ng.github.io.git
-cd powerapi-ng.github.io/docs/script/getting-started
-```
-
-2. Download the archive:
-```
-wget -c https://raw.githubusercontent.com/powerapi-ng/powerapi-ng.github.io/refs/heads/master/docs/script/getting_started.tar.gz -O - | tar -xz
-cd getting_started

 #### HWPC-Sensor and SmartWatts Configuration
 
-As described in the [HWPC-Sensor Documentation](./reference/sensors/hwpc-sensor.md#global-parameters) and in the [SmartWatts Documentation](./reference/formulas/smartwatts.md#global-parameters) 
+As described in the [HWPC-Sensor Documentation](./reference/sensors/hwpc-sensor.md#global-parameters) and in the [SmartWatts Documentation](./reference/formulas/smartwatts.md#global-parameters), 
 several parameters can be set, both globally and for specific Groups monitored for the sensor or the formula.
 
-The provided docker-compose.yaml file use configuration files and the **.env** to set those parameters.
-You can find example of both those configuration files in the archive under the **formula** and **sensor** directories.
