Este es el README para [el repositorio del sitio](https://gitea.nulo.in/Nulo/sitio).
Escuché [HOT DEMON B!TCHES NEAR U ! ! ! (de CORPSE y Night Lovell)](https://youtu.be/wqZnO71PBis) en loop para hacer la versión inicial del sitio.
## Compilar
Require [Zig](https://ziglang.org), shell, cmark (con cmark-dev) y Lua 5.1.
```
zig run compilar.zig -lc -lcmark
```
