 To do this, you need the path to the QGIS python folder, which should look like **C:\Program File\QGIS{n°version}\apps\Python{n°version}** and inside you'll find a python executable, a Scripts folder, Lib ... and in the Lib folder a site-package or ...-package folder containing folders for python libraries such as numpy.
 
-### Temporary link (just in the open terminal)
-
-The first step is to add the Windows paths to the QGIS python environment.  
-In a terminal (anywhere):
-```
-set PATH=C:\Program Files\QGIS 3.34.1\apps\Python39\;C:\Program Files\QGIS 3.34.1\apps\Python39\Scripts;%PATH%
-```
-**Warning**, change the paths according to your needs - this is just an example
-
-Second step, link the python:
-```
-set PYTHONPATH=C:\Program Files\QGIS 3.34.1\apps\Python39\Lib\site-packages
-```
-
-Now, in the terminal, when you type `python` you're using QGIS python, similarly with `pip`, `pip list` which you'll need to return QGIS python packages.  
-This command only works in the current terminal; if you open another terminal, the commands will be linked to the python installed on the machine or not found if you don't have python (easy to check with `python --version` if the python versions between your machine and QGIS are different).
-
-You can now install ign-borea (**Please note**, this command will be permanent, so you can open QGIS afterwards and type `import borea` in the python console).
-```
-pip install ign-borea
-```
-And use linked executables (However, executables are not permanent but linked to the terminal).
-
-This method also allows you to install other python packages that can be used in the QGIS python console.

-To establish a permanent link that can be accessed from any terminal. You need to add links to the Path variable and create the PYTHONPATH variable.  
-Open system environment variables (Windows key, then type `variable`)  
-![varenv](../image/varenv.png)  
-If the computer has several accounts, you can change the variables just for your account, otherwise change the system variables directly.  
-**Warning**, system variables are read before user variables. So if python is already installed and there's a C:\Python path in the system variable path, the python used will be that of the computer and not that of QGIS.  
-**Warning**, do not make any mistakes in the system variable paths, as this could lead to a system error, which could cause your computer to crash.

 The paths must be added to the Path variable:
