Hi Bruno, unfortunately I did't find a way to add the description since I am obtaining this information from the component minified code, not the file.

One way was to obtain it is from the automated docs that stencil creates (the ones i am showing on the notes tab) but they don't include a description either. This was the case until the day I made this article, but i checked that time and there was a PR to allow the description to appear, maybe it appears on the newest version of storybook, you should check it there.

Sorry I cannot help you more.
