docz
It has never been so easy to document your things!
... the look, feel and behave when required by leveraging GatsbyJS and Gatsby theme shadowing. There's a create-docz-app, which you can use to start new projects with docz even faster. This app is developed independently of the docz project, and is not officially supported. So use the app at your own risk. You can use create-docz-app as a replacement for create-react-app when you're creating a new project.
