 Confirm that this is showing a compatible version of Python 3.x. If not, and you have multiple versions of Python installed on your system, you may need to specify the appropriate version when creating the virtualenv:
-
- deactivate
- rmvirtualenv wagtailbakerydemo
- mkvirtualenv wagtailbakerydemo --python=python3.9
- python --version
+```bash
+deactivate
+rmvirtualenv wagtailbakerydemo
+mkvirtualenv wagtailbakerydemo --python=python3.9
+python --version

 Now we're ready to set up the bakery demo project itself:
-
- cd ~/dev [or your preferred dev directory]
- git clone https:/wagtail/bakerydemo.git
- cd bakerydemo
- pip install -r requirements/development.txt
+```bash
+cd ~/dev [or your preferred dev directory]
+git clone https:/wagtail/bakerydemo.git
+cd bakerydemo
+pip install -r requirements/development.txt
+```
 
 Next, we'll set up our local environment variables. We use [django-dotenv](https:/jpadilla/django-dotenv)
 to help with this. It reads environment variables located in a file name `.env` in the top level directory of the project. The only variable we need to start is `DJANGO_SETTINGS_MODULE`:
-
- cp bakerydemo/settings/local.py.example bakerydemo/settings/local.py
- cp .env.example .env
+```bash
+cp bakerydemo/settings/local.py.example bakerydemo/settings/local.py
+cp .env.example .env
+# `cp` is used for bash. Windows Command Prompt uses `copy`
+```
 
 To set up your database and load initial data, run the following commands:
-
- ./manage.py migrate
- ./manage.py load_initial_data
- ./manage.py runserver
+```bash
+./manage.py migrate
+./manage.py load_initial_data
+./manage.py runserver
