Do you want to request a feature or report a bug?
feature-> Online instructions do not describe my results
What is the current behavior?
Unable to create a new Strapi project
If the current behavior is a bug, please provide the steps to reproduce the problem

What is the expected behavior?
After running: strapi new my-project, I get questions about database type, name, port, etc.. Which is not mentioned on any of the documentation.
Anyhow, after answering all questions, I get the following error:
(node:7395) UnhandledPromiseRejectionWarning: Unhandled promise rejection. This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). (rejection id: 2)

*NOTE: the folder is never created
