Download and install these first:
- Git for Windows
- 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
- 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.
