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.
As an open source project we have limited resources, so the documentation is not as extensive as commercial software, but this site is designed to let you see what we have.
We are always interested in hearing from individuals and groups interested in HELM, so please get in touch via info@OpenHELM.org.
Code Orientation
If you want to get started with the code, and need a general overview please look through the code orientation video below. The slides are included for completeness, but much of the information was a live demo, so please note that they do not contain everything.
More detail is available in the application specific pages.
Forum
Please use the issue list in GitHub to post general HELM questions (and feel free to add answers to other peoples!).
Code defects should be discussed in the respective repository.
