Install Git & Python

Git

1. Download from git-scm.com/download/win
2. Run the installer — defaults are fine
3. On “Adjusting your PATH”, keep Git from the command line and also from 3rd-party software selected

git --version

Python 3.11+

1. Download from python.org/downloads/windows (3.11 or newer)
2. Run the installer — check Add python.exe to PATH at the bottom of the first screen
3. Finish install, open a new PowerShell window, then verify:

python --version
py -3.11 --version

Either command should show 3.11+. If only py works, use py -3.11 in the Windows install guide.
