When I start the first cell in my Jupyter notebook with:
# My Title
> ‘This blog post is cool. For more details check out my paper.’
everything works fine except for the link. Is this a missing feature or am I missing something here? 
Thanks for reading and above all, thank you so much for fastpages! 
This forum seems to convert .md-links automatically. What I wrote was a usual .md link with the label in square brackets and the actual link in parenthesis.
I believe you have to use HTML to make this work
<a href= …
Try it let me know if it works!
Thanks for your reply, @hamelsmu!
Now I have added the link as HTML: paper
Just as with markdown it gets rendered properly in the notebook, but in the blog post generated by fastpages one can see the actual code instead of a link 
Haha, this forum translates the HTML code to the actual link - just as it does with the md version ^^
You can now include HTML in the Description Only (not possible in other places for various reasons). Feature was added via https://github.com/fastai/fastpages/pull/269
You have to upgrade fastpages to get these changes. You can find examples of links in descriptions on https://fastpages.fast.ai/
Enjoy
It works! Thank you, thank you, thank you!!
