It will take many lines to describe each step.

In person, it could be explained if you did not understand a step.

drawings and video clips could be included.

The video needs to be compressed to reduce size and increase speed.

An index of all files needed

unique file name for each picture for each page

unique file name for each audio for each page

The display time must be set to match the audio time

To display online produce an MP4 video file

compress the video

create a link on a webpage to call the video file
