-## Installing with a Virtual Environment (Recommended)
+## Installing with Pipx (Recommended)
 
-### Windows
+[pipx](https://pipx.pypa.io/stable/) can install CLIs into isolated environments. view.py recommends using `pipx` for installation, and then using `view init` to initialize a virtual environment in projects. For example:
 
 ```
-> py -3 -m venv .venv
-> .\.venv\activate
-> pip install view.py
+$ pipx install view.py
+... pipx output
+$ view init
 ```
 
-### Linux/macOS
-
-```
-$ python3 -m venv .venv
-$ source .venv/bin/activate
-$ pip install view.py
-```

-!!! question "Why a virtual environment?"
-
-    view.py is a large package with lots of dependencies, as well as a big [extension module](https://docs.python.org/3/extending/extending.html). If you have no idea what a virtual environment is or why they're useful, take a look at [Python's documentation](https://docs.python.org/3/library/venv.html).
