+
+## What is this?
+
+This is a function that checks if a given character is an ASCII decimal.
+
+## When should I use this?
+
+Not often, as it’s relatively simple to do yourself.
+This package exists because it’s needed in several related packages, at which
+point it becomes useful to defer to one shared function.
+
+## Install
+
+This package is [ESM only][esm].
+In Node.js (version 12.20+, 14.14+, or 16.0+), install with [npm][]:
+
+```sh
+npm install is-decimal
+```
+
+In Deno with [Skypack][]:
+
+```js
+import {isDecimal} from 'https://cdn.skypack.dev/is-decimal@2?dts'
+```
+
+In browsers with [Skypack][]:
+
+```html
+<script type="module">
+  import {isDecimal} from 'https://cdn.skypack.dev/is-decimal@2?min'
+</script>
+```
+
+## Use
+
+```js
+import {isDecimal} from 'is-decimal'
+
+isDecimal('0') // => true
+isDecimal('9') // => true
+isDecimal('a') // => false
+isDecimal('💩') // => false
+```
+
+## API
+
+This package exports the following identifiers: `isDecimal`.
+There is no default export.
+
+### `isDecimal(character|code)`
+
+Check whether the given character code (`number`), or the character code at the
+first position (`string`), is decimal.
+
+## Types
+
+This package is fully typed with [TypeScript][].
+
+## Compatibility
+
+This package is at least compatible with all maintained versions of Node.js.
+As of now, that is Node.js 12.20+, 14.14+, and 16.0+.
+It also works in Deno and modern browsers.
+
+## Security
+
+This package is safe.
