+
+**[micromark][]** extension to support GitHub flavored markdown
+[strikethrough][] (~~like this~~).
+This syntax extension matches either the GFM spec (only two tildes work) or
+github.com (both one or two tildes, when they match, work).
+
+This package provides the low-level modules for integrating with the micromark
+tokenizer and the micromark HTML compiler.
+
+You probably shouldn’t use this package directly, but instead use
+[`mdast-util-gfm-strikethrough`][mdast-util-gfm-strikethrough] with
+**[mdast][]**.
+
+## Install
+
+[npm][]:
+
+```sh
+npm install micromark-extension-gfm-strikethrough
+```
+
+## API
+
+### `html`
+
+### `syntax(options?)`
+
+> Note: `syntax` is the default export of this module, `html` is available at
+> `micromark-extension-gfm-strikethrough/html`.
+
+Support strikethrough (~~like this~~).
+The export of `syntax` is a function that can be called with options and returns
+an extension for the micromark parser (to tokenize strikethrough; can be passed
+in `extensions`).
+The export of `html` is an extension for the default HTML compiler (to compile
+as `<del>` elements; can be passed in `htmlExtensions`).
+
+##### `options`
+
+###### `options.singleTilde`
+
+Whether to support strikethrough with a single tilde (`boolean`, default:
+`true`).
+Single tildes work on github.com, but are technically prohibited by the GFM
+spec.
