+
+:point_right: **Upgrading from v9.x to v10.x?** [Read the release notes!](https://github.com/sweetalert2/sweetalert2/releases/tag/v10.0.0)
+<br>If you're upgrading from v8.x, please [upgrade from v8 to v9](https://github.com/sweetalert2/sweetalert2/releases/tag/v10.0.0) first!
+<br>If you're upgrading from v7.x, please [upgrade from v7 to v8](https://github.com/sweetalert2/sweetalert2/releases/tag/v8.0.0) first!
+<br>If you're upgrading from v6.x, please [upgrade from v6 to v7](https://github.com/sweetalert2/sweetalert2/releases/tag/v7.0.0) first!
+
+:point_right: **Migrating from [SweetAlert](https://github.com/t4t5/sweetalert)?** [SweetAlert 1.x to SweetAlert2 migration guide](https://github.com/sweetalert2/sweetalert2/wiki/Migration-from-SweetAlert-to-SweetAlert2)
+
+---
+
+Installation
+------------
+
+```sh
+npm install --save sweetalert2
+```
+
+Or grab from [jsdelivr CDN](https://www.jsdelivr.com/package/npm/sweetalert2)
+:
+
+```html
+<script src="https://cdn.jsdelivr.net/npm/sweetalert2@10"></script>
+```
+
+
+Usage
+-----
+
+```html
+<script src="sweetalert2/dist/sweetalert2.all.min.js"></script>
+
+<!-- Include a polyfill for ES6 Promises (optional) for IE11 -->
+<script src="https://cdn.jsdelivr.net/npm/promise-polyfill@8/dist/polyfill.js"></script>
+```
+
+You can also include the stylesheet separately if desired:
+
+```html
+<script src="sweetalert2/dist/sweetalert2.min.js"></script>
+<link rel="stylesheet" href="sweetalert2/dist/sweetalert2.min.css">
+```
+
+Or:
+
+```js
+// ES6 Modules or TypeScript
+import Swal from 'sweetalert2'
+
+// CommonJS
+const Swal = require('sweetalert2')
+```
+
+Or with JS modules:
+
+```html
+<link rel="stylesheet" href="sweetalert2/dist/sweetalert2.css">
+
+<script type="module">
+  import Swal from 'sweetalert2/src/sweetalert2.js'
+</script>
+```
+
+It's possible to import JS and CSS separately, e.g. if you need to customize styles:
+
+```js
+import Swal from 'sweetalert2/dist/sweetalert2.js'
+
+import 'sweetalert2/src/sweetalert2.scss'
+```
+
+Please note that [TypeScript is well-supported](https://github.com/sweetalert2/sweetalert2/blob/master/sweetalert2.d.ts), so you don't have to install a third-party declaration file.
+
+
+Examples
+--------
+
+The most basic message:
+
+```js
+Swal.fire('Hello world!')
+```
+
+A message signaling an error:
+
+```js
+Swal.fire('Oops...', 'Something went wrong!', 'error')
+```
+
+Handling the result of SweetAlert2 modal:
+
+```js
+Swal.fire({
+  title: 'Are you sure?',
+  text: 'You will not be able to recover this imaginary file!',
+  icon: 'warning',
+  showCancelButton: true,
+  confirmButtonText: 'Yes, delete it!',
+  cancelButtonText: 'No, keep it'
+}).then((result) => {
+  if (result.value) {
+    Swal.fire(
+      'Deleted!',
+      'Your imaginary file has been deleted.',
+      'success'
+    )
+  // For more information about handling dismissals please visit
+  // https://sweetalert2.github.io/#handling-dismissals
+  } else if (result.dismiss === Swal.DismissReason.cancel) {
+    Swal.fire(
+      'Cancelled',
+      'Your imaginary file is safe :)',
+      'error'
+    )
+  }
+})
+```

+If you would like to contribute enhancements or fixes, please do the following:
+
+1. Fork the `sweetalert2` repository and clone it locally.
+
+2. Make sure you have [npm](https://www.npmjs.com/) or [yarn](https://yarnpkg.com/) installed.
+
+3. When in the SweetAlert2 directory, run `npm install` or `yarn install` to install dependencies.
+
+4. To begin active development, run `npm start` or `yarn start`. This does several things for you:
+ - Builds the `dist` folder
+ - Serves sandbox.html @ http://localhost:8080/ (browser-sync ui:  http://localhost:8081/)
+ - Re-builds and re-loads as necessary when files change
