How to make a Twitter share button?

Question

I've already googled it and found many options but none for what I want do exactly.

I basically want to make it possible for people to share a specific paragraph of my website on twitter using bootstrap.

I got to this point:
<a href="https://twitter.com/share" class="btn btn-social btn-twitter">
<i class="fa fa-twitter"></i> Share on Twitter</i> </a>
But i guess I'm missing something...
does anyone have any ideia?
