A Brunch skeleton is basically an application boilerplate that provides a good starting point for new applications. Skeleton can start you on your way with a specific pattern.
Creating new application with any skeleton is pretty simple:
# Simply create "dead simple" app without any opinions.
brunch new
# Create ES6 skeleton. "es6" is an alias from the table.
brunch new -s es6
# Same thing as above:
brunch new --skeleton brunch/with-es6
brunch new --skeleton https://github.com/brunch/with-es6
The complete skeletons list is hosted on GitHub — feel free to add any skeleton you create on your own!
