Hello Community,
I am starting a new site and am diving into sharing my site via Twitter. I have my Twitter card properly configured and it is a basic summary card and I am happy with it.
I am now trying to share this card. I am looking at this page:
https://dev.twitter.com/web/tweet-button
And under the “url” paramater under “Tweet text components” it states:
“A Twitter Card may be appear for a shared URL.”
How do I make this so that it will appear for a shared URL? 
Thank you for any assistance!
Michael
