HELM is both a notation, and a set of tools and applications that implement the notation. The tools are available as open source software released under the permissive MIT licence.
All the HELM code is on GitHub.
This wiki is the main source for information about HELM and its tools. Please have a look around and get in touch if you can’t find what you need, or want to connect with other HELM enthusiasts.
