README for Local set-up not sufficient for new users - missing Make install step

I just went through the instructions for the "Local Method" and it doesn't have enough detail for a fresh set-up. There is no step covering installing make.

Instructions I used with @cmacfarl 's help:

Open PowerShell with "Run as Administrator"
Follow instructions from https://chocolatey.org/install
run `Set-ExecutionPolicy Bypass -Scope Process -Force; [System.Net.ServicePointManager]::SecurityProtocol = [System.Net.ServicePointManager]::SecurityProtocol -bor 3072; iex ((New-Object System.Net.WebClient).DownloadString('https://community.chocolatey.org/install.ps1'))`
run `choco install make`

Also recommend:

1. Move the local git install step into the local section
2. Add more detail (like a default recommendation) for what you mean by Git Install on local machine
