Download and install these first:

- [NodeJS](https://nodejs.org/)
- [Git for Windows](https://git-scm.com/downloads)
    + During installation, on the options screen with the check boxes about what to install, check the box for TrueType fonts
    + On the screen with three radio button options about the shell and Windows Command Prompt, choose the second option
    + Go with the default options for the rest of the installation
- [SourceTree](https://www.sourcetreeapp.com/download)
    + This is similar to GitHub's app, but more powerful and flexible

Then open the Git Bash shell (Start > Git > Git Bash) and continue with the next file below.
