One Good Tutorial is an instructional resource for people who are documenting scientific software. It's delivered as a static website canonically served at https://onegoodtutorial.org. The main idea is right there in the name: the most important thing is that your software's documentation includes one good tutorial. You need a bit more than that, but not much more: the One Good Tutorial software documentation checklist defines eight core elements of scientific software documentation. The resource also includes a playbook you can follow to prepare these eight elements with a minimum of angst and a number of supporting in-depth guides. The materials deposited with Zenodo include the built One Good Tutorial static website and its underlying source code.
