How to download/share existing post on dashboard

As a member, how do I share and download a post by others that I see in my dashboard?

An example is the welcome post by the Ghost platform. Is there a way for me to download this post and share to other social media accounts?

View the post outside the dashboard and your theme possibly has inline social media share icons. What do you mean by download?

Or are you talking about setting up an integration to share posts to social media as you publish them?

Thank you for the reply! I went to view the themes, and I do see some social media icons under some articles. How do I add those icons to my articles as well (ie. how to set up an integration to share posts to social media as you publish them?) Is it through Zapier? So if I connect Ghost with Twitter through Zapier, the twitter icons will appear under my articles?

Next, is it possible for me to re-share some articles to individual members in Ghost? (Like how you can send posts to others in Instagram)
