+
+## Introduction
+
+`chartjs-adapter-intl` is a date adapter for [Chart.js](https://www.chartjs.org/) that uses the native `Intl.DateTimeFormat` API for date formatting and parsing.
+
+Requires [Chart.js](https://github.com/chartjs/Chart.js/releases) **3.0.0** or later.
+
+**Note:** once loaded, this adapter overrides the default date-adapter provided in Chart.js (as a side effect).
+
+## Installation
+
+You can install this adapter via pnpm:
+
+```sh
+pnpm install chartjs-adapter-intl
+```
+
+via npm:
+
+```sh
+npm add chartjs-adapter-intl
+```
+
+via yarn:
+
+```sh
+yarn add chartjs-adapter-intl
+```
+
+### CDN
+
+By default, `https://cdn.jsdelivr.net/npm/chartjs-adapter-intl` returns the latest (minified) version, however it's [highly recommended](https://www.jsdelivr.com/features) to always specify a version in order to avoid breaking changes. This can be achieved by appending `@{version}` to the URL:
+
+```html
+<script src="https://cdn.jsdelivr.net/npm/chart.js@^3"></script>
+<script src="https://cdn.jsdelivr.net/npm/chartjs-adapter-intl"></script>
+```
+
+Read more about jsDelivr versioning on their [website](http://www.jsdelivr.com/).
+
+## Usage
+
+To use this adapter, you need to import it into your project. The adapter will automatically register itself with Chart.js.
+
+```javascript
+import { Chart } from 'chart.js';
+import 'chartjs-adapter-intl';
+
+const config = {
+  type: 'line',
+  data: {
+    datasets: [{
+      data: [
+        { x: '2023-01-01T00:00:00Z', y: 10 },
+        { x: '2023-01-02T00:00:00Z', y: 20 }
+      ]
+    }]
+  },
+  options: {
+    scales: {
+      x: {
+        type: 'time',
+        time: {
+          unit: 'day'
+        }
+      }
+    }
+  }
+};
+
+const myChart = new Chart(document.querySelector('#myChart'), config);
+```
+
+## Configuration
+
+This adapter supports the following configuration options:
+
+- `locale`: The locale to use for formatting dates. Defaults to `'en-US'`.
+
+```javascript
+const config = {
+  type: 'line',
+  data: {
+    datasets: [{
+      data: [
+        { x: '2023-01-01T00:00:00Z', y: 10 },
+        { x: '2023-01-02T00:00:00Z', y: 20 }
+      ]
+    }]
+  },
+  options: {
+    scales: {
+      x: {
+        type: 'time',
+        adapters: {
+          date: {
+            locale: 'fr-FR'
+          }
+        },
+        time: {
+          unit: 'day'
+        }
+      }
+    }
