 ## Installation and Documentation
 
+Unitary uses Python 3.12. It's recommended to use a virtual environment for installing Unitary to
+avoid interfering with other system packages:
+
+```sh
+python3.12 -v venv ~/unitary
+source ~/unitary/bin/activate
+```
+
+Unitary can then be installed within that virtual environment.
+
 Unitary is not available as a PyPI package. Please clone this repository and
 install from source:
 
-    cd unitary/
-    pip install .
+```sh
+cd unitary/
+pip install .
