# [Blog in a Matrix](https://bloginamatrix.xyz)
New server side rendered blog site written in Nim.
New single page blog site application written in Nim.
Articles/blogs written in markdown using [Joplin](https://github.com/laurent22/joplin/ "The best notes app/markdown editor ever made.") then exported as `HTML` to the `/src/public` directory. Joplin has support for [the extended markdown syntax](https://github.com/laurent22/joplin/blob/dev/readme/markdown.md), [KaTeX](https://khan.github.io/KaTeX/), and [Mermaid.js](https://mermaidjs.github.io/) out of the box. The syntax can be farther extended with [plugins](https://github.com/joplin/plugins/) (e.g. [music sheet notation](https://github.com/joplin/plugin-abc-sheet-music)).
