Examples

To help you get started with Mantil, we prepared a set of examples and tutorials where you can see how to use Mantil in practice and how to organize your project. Besides just learning from examples, you can use those to bootstrap your own project with mantil new <my_project> --from <template_name>.

If there is any other example you would like to see, let us know in Mantil Slack Community.
