macOS:

For the installation, specifically macOS, we do not mention Homebrew as a prerequisite for the installation. Xcode Install Tools are also required, but Homebrew takes care of that, but perhaps because I have Xcode already?

Running brew install github/gh/gh without Homebrew results in command not found error.

Also, there is no mention of the SSH or HTTPS authentication, nor the subsequent browser authentication.

I am not sure what else I am missing?

Linux:

If authenticating with a personal access token (PAT), you need to add this to your gh config.

~/.config/gh/config.yml

yaml
github.com:
  - user: $GITHUB_USERNAME
    oauth_token: $PERSONAL_ACCESS_TOKEN

Windows:

Uninstalling

Directions to do an uninstall would be great too

Minimum req's

Each OS should have the following:

• dependencies, prerequisites for installing
• instructions for installing
• instructions for authenticating
• instructions for upgrading
• instructions for uninstalling
