This plugin is not necessary

According to this blog post kramdown can easily support Katex without this plugin. See the section "Method 2".

Thanks @makeworld-the-better-one! I was having troubles with this plugin and a newer version of jekyll. But your solution works as well! It also seems to be faster.

It requires some changes though, such as changing single dollars into double dollars.

For me it only worked with the duktape js engine.

Loads fine for me. You could try this archived version I guess: https://web.archive.org/web/20210416031226/https://gendignoux.com/blog/2020/05/23/katex.html

@makeworld-the-better-one Thanks for this info! This plugin hasn't been maintained so it's great to find a working solution. IIUC, all jekyll users who have kramdown as the markdown engine can benefit. Is that correct? I will update info for this plugin accordingly.

I believe so. I'm just going off the two blog posts I linked to in the original comment.
