Getting started

The best way to get started is to read the guide to download, install and start using Butano. After that, there are various examples explaining most aspects of the engine. At last, check how to import your own assets in a game and take a look at the modules page. The frequently asked questions (FAQ) are worth a look too.

Contact and support
