Customization

The complete list of plugins, settings, and utilities is given below. The sbt-typelevel-ci-release and sbt-typelevel super-plugins automatically load most of them. The diagram at the bottom of the page shows their inter-dependencies.

Instead of using the super-plugins, for finer-grained control you can always add plugins individually to your project and even build your own custom super-plugin.
