endoflife.date Recommendations

A talk about the importance of documentation, and what it takes to get it right. I cover learnings from the endoflife.date project, and recommendations I wrote down so other projects can follow them to better document their support lifecycles.

The talk covers best practices around documenting your release cadence, processes, EOL dates, versioning schemes, and various gotchas. There are lots of examples to showcase what is good vs bad (and why).

The talk comes out of my experience of creating endoflife.date as an open-source community project, and documenting the lifecycles and EOL dates of more than 100 products.

It is based on the recommendations listed at https://endoflife.date/recommendations. Presented at the FOSS United Meetup in Bangalore, June 2022.
