The HELM specification is the definitive document on how to use HELM and should always be consulted first.
However, our users have learnt from their the real-world experience of using HELM and we try to capture that knowledge in this best practices section. We have included the main issues that have come to our attention, but are always open to add more.
Please do let us know if you have an item you would like to add, or a question on HELM. You can use the issue list or email us at info@openHELM.org
