Testing … pls ignore

Adding a plugin to show maths using LaTeX in you wordpress posts is a pain.

The worst plugin experience was with WP KaTeX.

WP KaTeX : absolutely no documentation to help usage, after plugin installation. No mention of limitations or restrictions.  No description for the   recommended  jsDelivr CDN  addon.  No examples or sample sites or tutorials or support forums.

$ latex
\frac{1}{\pi} = \frac{2\sqrt{2}}{9801}\sum\limits_{k=0}^\infty\frac{(4k)!(1103+26390k)}{(k!)^4 (396^{4k})}
