When you say DevOps

A presentation which further explores automation as part of DevOps principles. That automation is best fulfilled by adopting continuous integration and delivery practices. It also stresses that even in the age of GitHub flow mainline (trunk-based or master-based) development makes sense for probably most of the code we are writing and that we are often blindly adopting processes suitable for large open source projects.

There is an example given during presentation which can be found at https://github.com/frzng/toggles-example. Original Keynote presentation can be found at https://www.icloud.com/keynote/0ASyPrXNsy-wMueAVNkFOfYQw#When_you_say_DevOps.
