Cheatsheets are two-page PDFs loaded with short examples and even shorter explanations. They push you over all the little roadblocks.
When you need to find detailed information on how to get started with Hail, examples of Hail use, and how a function works: the reference document is your go to. To do a quick search of a Hail function, try out the search bar in the documentation.
When you reach a blocking issue with your analysis using Hail, and you think you are unable to find an answer to your question via the documentation, search through or ask a question on our Forum! It is highly recommended -- your question may be able to serve another person in our ever growing Hail community.
