+If you need to save really large files bigger then the blob's size limitation or don't have
+enough RAM, then have a look at the more advanced [StreamSaver.js][7]
+that can save data directly to the hard drive asynchronously with the power of the new streams API. That will have
+support for progress, cancelation and knowing when it's done writing
+
+FileSaver.js
+============
+
+FileSaver.js is the solution to saving files on the client-side, and is perfect for
+web apps that generates files on the client, However if the file is coming from the
+server we recommend you to first try to use [Content-Disposition][8] attachment response header as it has more cross-browser compatiblity.
+
+Looking for `canvas.toBlob()` for saving canvases? Check out
+[canvas-toBlob.js][2] for a cross-browser implementation.
+
+Supported Browsers
+------------------
+
+| Browser        | Constructs as | Filenames    | Max Blob Size | Dependencies |
+| -------------- | ------------- | ------------ | ------------- | ------------ |
+| Firefox 20+    | Blob          | Yes          | 800 MiB       | None         |
+| Firefox < 20   | data: URI     | No           | n/a           | [Blob.js](https://github.com/eligrey/Blob.js) |
+| Chrome         | Blob          | Yes          | [2GB][3]      | None         |
+| Chrome for Android | Blob      | Yes          | [RAM/5][3]    | None         |
+| Edge           | Blob          | Yes          | ?             | None         |
+| IE 10+         | Blob          | Yes          | 600 MiB       | None         |
+| Opera 15+      | Blob          | Yes          | 500 MiB       | None         |
+| Opera < 15     | data: URI     | No           | n/a           | [Blob.js](https://github.com/eligrey/Blob.js) |
+| Safari 6.1+*   | Blob          | No           | ?             | None         |
+| Safari < 6     | data: URI     | No           | n/a           | [Blob.js](https://github.com/eligrey/Blob.js) |
+| Safari 10.1+   | Blob          | Yes          | n/a           | None         |
+
+Feature detection is possible:
+
+```js
+try {
+    var isFileSaverSupported = !!new Blob;
+} catch (e) {}
+```
+
+### IE < 10
+
+It is possible to save text files in IE < 10 without Flash-based polyfills.
+See [ChenWenBrian and koffsyrup's `saveTextAs()`](https://github.com/koffsyrup/FileSaver.js#examples) for more details.
+
+### Safari 6.1+
+
+Blobs may be opened instead of saved sometimes—you may have to direct your Safari users to manually
+press <kbd>⌘</kbd>+<kbd>S</kbd> to save the file after it is opened. Using the `application/octet-stream` MIME type to force downloads [can cause issues in Safari](https://github.com/eligrey/FileSaver.js/issues/12#issuecomment-47247096).
+
+### iOS
+
+saveAs must be run within a user interaction event such as onTouchDown or onClick; setTimeout will prevent saveAs from triggering. Due to restrictions in iOS saveAs opens in a new window instead of downloading, if you want this fixed please [tell Apple how this WebKit bug is affecting you](https://bugs.webkit.org/show_bug.cgi?id=167341).
+
+Syntax
+------
+### Import `saveAs()` from file-saver
+```js
+import { saveAs } from 'file-saver';
+```
+
+```js
+FileSaver saveAs(Blob/File/Url, optional DOMString filename, optional Object { autoBom })
+```
+
+Pass `{ autoBom: true }` if you want FileSaver.js to automatically provide Unicode text encoding hints (see: [byte order mark](https://en.wikipedia.org/wiki/Byte_order_mark)). Note that this is only done if your blob type has `charset=utf-8` set.
+
+Examples
+--------
+
+### Saving text using `require()`
+```js
+var FileSaver = require('file-saver');
+var blob = new Blob(["Hello, world!"], {type: "text/plain;charset=utf-8"});
+FileSaver.saveAs(blob, "hello world.txt");
+```
+
+### Saving text
+
+```js
+var blob = new Blob(["Hello, world!"], {type: "text/plain;charset=utf-8"});
+FileSaver.saveAs(blob, "hello world.txt");
+```
+
+### Saving URLs
+
+```js
+FileSaver.saveAs("https://httpbin.org/image", "image.jpg");
+```
+Using URLs within the same origin will just use `a[download]`.
+Otherwise, it will first check if it supports cors header with a synchronous head request.
+If it does, it will download the data and save using blob URLs. 
+If not, it will try to download it using `a[download]`.
+
+The standard W3C File API [`Blob`][4] interface is not available in all browsers.
+[Blob.js][5] is a cross-browser `Blob` implementation that solves this.
+
+### Saving a canvas
+```js
+var canvas = document.getElementById("my-canvas");
+canvas.toBlob(function(blob) {
+    saveAs(blob, "pretty image.png");
+});
+```
+
+Note: The standard HTML5 `canvas.toBlob()` method is not available in all browsers.
+[canvas-toBlob.js][6] is a cross-browser `canvas.toBlob()` that polyfills this.
+
+### Saving File
+
+You can save a File constructor without specifying a filename. If the
+file itself already contains a name, there is a hand full of ways to get a file
+instance (from storage, file input, new constructor, clipboard event). 
+If you still want to change the name, then you can change it in the 2nd argument.
+
+```js
+// Note: Ie and Edge don't support the new File constructor,
+// so it's better to construct blobs and use saveAs(blob, filename)
+var file = new File(["Hello, world!"], "hello world.txt", {type: "text/plain;charset=utf-8"});
+FileSaver.saveAs(file);
+```
