Details on how to do this task: Make software accessible
I successfully downloaded GitHub for Mac - this was a little challenge because I'm running 10.8 (because of other software I use) and GitHub isn't natively supporting below 10.9 now. But, I found a link for an older version that lets me do what I need to: https://web.archive.org/web/20140704072852/https://mac.github.com/
This made it easy to copy my already-organized code to a repo (where I added author, licenses, readme, etc.)
Next step will be to get a DOI for this - once I have a little more info on publications to put into the Readme. One thing that is slightly unclear is whether I will be able to update things in the release (e.g. Workflow, etc.) before sharing it. https://guides.github.com/activities/citable-code/
