 This handbook uses [mkdocs](https://www.mkdocs.org/) to render the handbook written as a collection of markdown files into a website.
 If you would like to render it locally, you would need to create and configure a python environment according to configuration provided in [requirements.txt](./requirements.txt) file, e.g. via
 
-   python3 -m venv venv && source venv/bin/activate && python3 -m pip install -r requirements.txt
+    python3 -m venv venv && source venv/bin/activate && python3 -m pip install -r requirements.txt
 
 And your current session would already be using that virtual Python environment, which you could deactivate by executing `deactivate` command.
 If in the future you would need to activate it, just `source venv/bin/activate` again.
