# LaTeX

LaTeX is the most popular TeX Dialect. It can use all LuaTeX registers, which
means you can create a bigger document than PlainTeX.

`main.tex`:

```tex
\documentclass{article}
\begin{document}

Hello, \LaTeX!
$$\sum_{n = 1}^\infty\frac1{n^2} = \frac{\pi^2}{6}$$

\end{document}
```

```sh
lx add -b lualatex
lx shell --build
lualatex main.tex
```
