Embed Video from YouTube, Vimeo and etc
First of all you need to get your video embed code from video service provider (YouTube in this case).
Select "Video" node in the project tree view.
Click "Add video from YouTube, Vimeo..."
Enter name to refer to this video and embed code from service provider.
Now your video is in project's video library and you can embed it into topics.
Select a topic to insert video into, place cursor where you want your video to appear and click "Insert Video" on the editor tool bar.
Video placeholder appears in the position of cursor. Now Helpinator will insert your YouTube video into compiled documentation if the selected output format supports video.
