The Guidelines are organized so that readers can begin where their interests lie; there was no expectation that someone would start on page one and read each chapter in order until the end. Given the conceptual connections and relationships among the topics covered in the chapters, the chapters were developed in a collaborative environment where there was communication and engagement across chapter teams. Each chapter begins with a list of its key, high-level messages, includes references to other chapters and uses icons and case studies to draw attention to key topics covered elsewhere in the Guidelines. Additionally, there is a shorter Overview publication with the same design and use of icons to introduce each of the chapters in 3-5 pages by highlighting key messages.
