(PLEASE DO NOT DELETE THIS HEADER OR CREDIT!)
User customizable settings below!
Please refer to my guide over on https://virtualobserver.moe/ayano/comment-widget if you're confused on how to use this.
The IDs at the top are a requirement but everything else is optional!
Do not delete any settings even if you aren't using them! It could break the program.
After filling out your options, just paste this anywhere you want a comment section
(But change the script src URL to wherever you have this widget stored on your site!)
<div id="c_widget"></div>
<script src="comment-widget.js"></script>
Have fun! Bug reports are encouraged if you happen to run into any issues.
