YouTube chapters help the viewer jump to the needed step of an instruction. For them to work like a table of contents, name the result of each segment and check the timestamps in the finished video. A list of nice titles without exact transitions will only make viewing harder.
Build the table of contents after editing
YouTube requires for manual chapters the first timestamp 00:00, at least three timestamps in ascending order, and each chapter to be at least ten seconds long. Timestamps with titles are added to the video description; manual chapters replace automatic ones. If the feature is unavailable, the help page suggests checking access to advanced features.
In a conditional two-minute instruction, you can mark out 00:00 "What to prepare," 00:25 "Assembling the base," 01:20 "Checking stability." This is a teaching example, not a universal markup. Real boundaries are chosen based on the content of your own file.
Check the start of each step
Open the video as a viewer and click each chapter. The transition should lead to the moment from which the new step is clear, not to the middle of a sentence. Listen to a few seconds before and after the boundary. If the tool is shown before the explanation, the start of the chapter may need to be shifted.
Avoid titles like "Very important" and "Secret": they do not help find a specific answer. Better are "How to secure the leg" or "What to check before turning it on." Do not add to the title a product that is not in that segment.
If the chapters did not appear
First recheck the format and intervals, then the limitations of the video itself and the availability of the feature. Automatic chapters do not appear on all eligible videos. A manual list of timestamps and a clear description are still useful, but you should not declare interface chapters ready without checking the player.
After trimming or another edit, go through all the transitions again: the old seconds may no longer match the steps. Chapters organize the content, while growth in watch-through and inquiries is checked separately using data, without promising an automatic effect.
Outline: 1 — divide the instruction into completed steps; 2 — set exact timestamps; 3 — check the transitions in the player.

Check the list of timestamps before inserting it into the description
In the chapter check, insert the time and title of each section on a separate line. Specify the full duration of the video so the tool can check the last chapter. Without it, only the order of timestamps and the length of the intermediate segments are available; the end of the last chapter is unknown.
Teaching example: 00:00 "Preparation," 00:30 "Assembly," 02:10 "Check" for a video 03:00 passes the check. For a video 02:15, the last chapter is only 5 seconds — you need to change the boundary or the structure of the table of contents. Download the checked text, insert it into the description, and check all transitions in YouTube. The form limit of up to 200 lines is a limit of the Boosted tool, not a stated limit of the platform.
