This cli tool's purpose is to offer an interactive experience to learn how the stacking workflow, well, works.
It does this with the help of git-town and its nested feature branches support.
You can find the generated documentation in .md and man pages format in the docs directory.
For this tool to work you'll need to have git-town installed already. Just follow the steps in the installation page and then proceed with the setup.
In the setup you'll also be asked for a GitHub token so that git-town can then make Pull Requests. This step is done interactively so you can set it up when running the setup command.
