# Configuration

> The two config files, the Vite plugins, and the file extensions norns registers.

- [svelte.config.js](/norns/config/svelte-config) — `nornsConfig()` and its defaults.
- [Vite plugin](/norns/config/vite-plugin) — `nornsCivetPlugin()`, `pugTailwindExtract()`, and the Vite options that matter.
- [File extensions](/norns/config/file-extensions) — `.n`, `.c`, `.civet`, and how they map onto SvelteKit's files.
