+# rehype-starry-night
+
+## What is it?
+
+It's a [rehype](https://github.com/rehypejs/rehype) plugin to transform `<code>` blocks with language attribute with @wooorm's [starry-night](https://github.com/wooorm/starry-night) code syntax highlighter.
+
+You may want to try this if you were unhappy with results from [prism](https://github.com/PrismJS/prism/) or [shiki](https://github.com/shikijs/shiki).
+
+## How to use?
+
+1. Install the plugin with npm (`npm install rehype-starry-night`)
+2. Use in a unified pipeline like this:
+
+```js
+import fs from 'node:fs/promises'
+import { unified } from 'unified'
+import remarkParse from 'remark-parse'
+import remarkRehype from 'remark-rehype'
+import rehypeStringify from 'rehype-stringify'
+import rehypeStarryNight from 'rehype-starry-night'
+
+const file = await unified()
+  .use(remarkParse)
+  .use(remarkRehype)
+  .use(rehypeStarryNight)
+  .use(rehypeStringify)
+  .process(await fs.readFile('example.md'))
+
+console.log(String(file))
+```
+
+## Configure?
+
+The options you can pass are the same as the original project, which you can find [here](https://github.com/wooorm/starry-night#createstarrynightgrammars-options).
+
+Since _most of the time_ this plugin will be used in a larger context which involves pre-processing of markdown, i took the freedom to default `grammars` to `all` which means all languages should be supported out of the box. There's no extra cost at install since this `all` is brought by starry night, and should not impact performance as long as you don't run this in the browser.
