brew install gh

# upgrade
brew upgrade gh

# verify GitHub status
gh auth status
gh --version

# make direct Pull Requests
git config --global --add --bool push.autoSetupRemote true

# set name and email - used for commits - by directory
vi ~/.gitconfig

# Global defaults (used if no includeIf matches)

  name = Default Name
  email = default@example.com

[core]
  editor = vim
  autocrlf = input

# -------------------------
