+## Installing Python Packages for Emio Labs
 
-To do this:
+If you are creating your own lab, you might need to install Python packages that are not shipped with the embedded Emio Labs Python.
+To install these packages for your lab, you can add a `python-button` to the markdown file:
+    ```markdown
+    #python-button(pyargs=["-m", "pip", "install", "--target", "assets/labs/<LAB_NAME>/modules/site-packages", "MYPACKAGENAME"])
+    ```
+or if you have a requirement.txt file:

+    ```
 
-1. Find the Python installation of Emio Labs by going to the installation folder of Emio Labs, for example on Windows that might be `C:\Users\<USERNAME>\AppData\Local\Programs\emio-labs` .
-2. There should be a folder `resources\sofa\bin\python`. This is where the Python running with Emio Labs is.
-3. Open a terminal in this folder ( e.g. `C:\Users\<USERNAME>\AppData\Local\Programs\emio-labs\resources\sofa\bin\python`).
-4. To install the Python package of name `lepackage`, type in `python -m pip install lepackage` 
-5. If admin rights are necessary, accept or type in the admin password when prompted
+Then, on the page of your lab in the Emio Labs application, clicking on the Python button <img className="drop-shadow" src="/img/logo_python.png" alt="python-icon" style={{borderRadius:0,width:20}}/> will install the extra Python packages in the `modules/site-packages` directory of your lab.
 
 :::warning
 If you are on MacOS, there is no Python shipped with Emio Labs. Use the Python you installed in the [installation process](#installation)
