Not sure why it doesn't work - i've followed the steps and the md files are properly formatted.

I've been using TeX for 5 years now and heavily depend on it. Hope I can use LaTeX with Gatsby.

Seems to be working here https://using-remark.gatsbyjs.org/katex/ perhaps check out the example site to see if you're missing something?

I followed the instructions of gatsby-remark-katex but unable to see the latex formula. Did anyone observe this recently?

• gatsby-remark-katex@3.1.2
• katex@0.10.2
• gatsby-transformer-remark@2.6.9

On my end I get a weird behavior, everything between dollar signs dissapears, but it isn't rendered as TeX.

I ran into the same issue. Try this config instead. @miguelgondu @Jiang-Li

	{
			resolve: `gatsby-plugin-mdx`,
			options: {
				defaultLayouts: {
					default: require.resolve(`./src/components/mdxLayout.js`)
				}
				remarkPlugins: [ require('remark-math'), require('remark-html-katex') ]
