YouTube is making it easier to navigate longer videos with its new “chapters” feature, the video streaming site announced. After receiving positive feedback on chapters during a testing period, the feature will stay on YouTube permanently as of May 28th, YouTube told Engadget in a statement. Chapters are available on the web and in the Android and iOS YouTube apps.

Viewers can click on chapters to jump to a specific part of a video and rewatch video clips —  a more convenient alternative to scrubbing. Chapters are visible at the bottom of the video player and show timestamps from the video description. Chapters are optional and will only appear if a video creator chooses to include them. Creators can only use chapters if the first chapter starts at 0:00, the video has at least three time stamps or chapters and if each chapter is at least 10 seconds.
