How to setup Botium Box

As per the details available at below link: https://medium.com/@floriantreml/botium-in-a-nutshell-part-3-automating-chatbot-tests-6c4e9e85121e

"Botium Box includes management of your chatbot capabilities, so you won’t have to write those botium.json files by hand. Instead the configuration is done within an easy 3-step-wizard"

Can someone let me know how to download and setup Botium Box on local machine ? Is there any user guide/handbook available? Please suggest.

Thanks, Ravi
