Hello !
I succeeded in adding LaTeX on my nodebb forum but my solution is bad for maintenance (all plugin I found to do that had defaults so I made my own work)... I think there is a greater/more elegant way ; here is the reason for this message 
.
Here is my method for now :
- I forked nodebb-plugin-markdown (named it nodebb-plugin-markdown-YA).
- I added into package.json these dependencies : katex and markdown-it-texmath.
- I copied katex.min.css from katex to nodebb-plugin-markdown-YA/public/less/katex.min.less.
- I copied "fonts" dir from katex to "nodebb/public".
- I changed nodebb-plugin-markdown/index.js (bof, bof...
). Here is the diff between nodebb-plugin-markdown/index.js and nodebb-plugin-markdown-YA/index.js :

Is there a greater way to do these things keeping nodebb-plugin-markdown unchanged and installed ? I can write another plugin to apply my changes (add LaTeX with markdown-it-texmath and katex and remove markdown-it-checkbox use) but is it really possible and, if yes, with which hooks ?
It would be really simpler for maintenance (and also more beautiful... )...
Thanks in advance for help !
