+
+CLI Helpers is a Python package that makes it easy to perform common tasks when
+building command-line apps. It's a helper library for command-line interfaces.
+
+Libraries like `Click <http://click.pocoo.org/5/>`_ and
+`Python Prompt Toolkit <https://python-prompt-toolkit.readthedocs.io/en/latest/>`_
+are amazing tools that help you create quality apps. CLI Helpers complements
+these libraries by wrapping up common tasks in simple interfaces.
+
+CLI Helpers is not focused on your app's design pattern or framework -- you can
+use it on its own or in combination with other libraries. It's lightweight and
+easy to extend.
+
+What's included in CLI Helpers?
