Trunk-Based Development And Branch By Abstraction is a book by Paul Hammant. 350 pages with plenty of diagrams, charts, and the culmination of over 15 years of getting enterprises to adopt "TBD" without stopping regular development and delivery of business value.

Trunk-based development and branch by abstraction super reference. All the aspects of this industry leading branching model covered.

In addition to reference information, there are chapters helping you understand how to get your company from a bad branching model (and slow release cadence) to trunk-based development, CI, CD and all that comes from that. Oh, and a higher release cadence as a result.
