+- On Linux/Mac:
+
+```
+python3 -m venv venv
+source venv/bin/activate

+#### 4. Install dependencies:
 
 ```
 pip install -r requirements.txt
 ```
-> if you are on a different python version, for example python3.x you may have to replace `pip` with `pip3`

+- Run all tests with the default Python interpreter:
 
 ```
 pytest
 ```
 
-> Please keep some patience - If you are doing it for the first time, it will take a little while to verify and download the browser drivers
+- Run all tests with every installed/supported Python interpreter:
 
-## Execute a specific example

+# For a specific environment, run: "tox -e <env>" (i.e.: "tox -e py313")
