+==What is a Virtual Environment?==
+A virtual environment is an isolated directory that contains its own Python interpreter, libraries, and packages. It allows you to manage project dependencies independently, preventing conflicts with other projects or system-wide Python installations.
+<sxh shell>
+# create the virtual environment
+python3 -m venv .venv
+# activate it
+source .venv/bin/activate
+# this should point to the python binary in your virtual environment
+which python
+# install dependencies in the virtual env
+python -m pip install -r requirements.txt
