Once you're ready with your article, don't forget to add a description to it since it's an important part of displaying it in the search engines and also sharing it in the social media.
Once you click on 'Article' settings, a properties window will open up where you'll be able to add the description. Remember to keep it simple and short (max up to 3 sentences).
If you're ready, don't forget to save the changes and you should be good to go!
