Thank you for developing this great package, it seems perfect for adding a list of publications to github pages! I am using it as intended, but am currently testing my site locally with the BretFisher/jekyll-serve docker container rather than live on github pages.
I've added <script src="https://code.jquery.com/jquery-1.12.4.js"></script> to _includes/head.html, and bibere.scss to _sass/, along with the required _includes/bibere files and demo _data/bibere/ yaml files.
Including paper.html for one paper works okay, though without styling:

However, using byyear.html breaks at the first publication at the <code> tag:

Am I using bibere incorrectly, or could this be breaking due to the particular docker container I am hosting it in? Any suggestions on how to fix the <code> section of byyear.html and how to get the bibere.scss to be applied?
