+
+[remark] plugin to implement [SmartyPants]. Now with 100% more ESM!
+
+## Installing
+
+```sh
+# using npm
+npm install remark-smartypants
+
+# using yarn
+yarn add remark-smartypants
+```
+
+## Usage
+
+Example using [remark]:
+
+```js
+import remark from "remark";
+import smartypants from "remark-smartypants";
+
+const result = await remark().use(smartypants).process("# <<Hello World!>>");
+
+console.log(String(result));
+// # «Hello World!»
+```
+
+I created this plugin because I wanted to add SmartyPants to [MDX]:
+
+```js
+import mdx from "@mdx-js/mdx";
+import smartypants from "remark-smartypants";
+
+const result = await mdx("# ---Hello World!---", {
+  remarkPlugins: [smartypants],
+});
+```
+
+Note that angle quotes in the former example (`<<...>>`) are probably impossible in MDX because there they are invalid syntax.
+
+This plugin uses [retext-smartypants](https://github.com/retextjs/retext-smartypants) under the hood, so it takes the same options:
+
+```js
+const result = await remark()
+  .use(smartypants, { dashes: "oldschool" })
+  .process("en dash (--), em dash (---)");
+```
