    Commitizen has two command line tools:

      1) commitizen -- used for installing adapters into your project
      2) git-cz     -- used for making commits according to convention
                       note: you can run 'git cz' if installed with -g

    Generally if you're using someone else's repo and they've already set up an
    adapter, you're going to just be running:

         git-cz

    However, if you create a new repo and you want to make it easier for future
    contributors to follow your commit message conventions using commitizen then
    you'll need to run a command like this one to add this adapter to your config:

         commitizen init cz-conventional-changelog --save

    You should swap out cz-conventional-changelog for the NPM package name of the
    adapter you wish you install in your project's package.json.

    Detailed usage:

      1) commitizen <sub-command>

         init <adapter-npm-name> [args]

           description: Install a commitizen adapter from npm and adds it to your
                        config.commitizen in your package.json file.

           args:
             --save         Install the adapter to package.json dependencies
             --save-dev     Install the adapter to devDependencies
             --save-exact   Install an exact version instead of a range
             --force        Force install the adapter, even if a previous one exists.

      2) git-cz <any regular git commit arguments>

          description: Runs the commitizen prompter, asking you questions so that you
                       follow the commit conventions of the repository of the current
                       directory.

                       note: git-cz may even be run as 'git cz' if installed with -g.
