+FileSaver.js
+============
+
+FileSaver.js implements the HTML5 W3C `saveAs()` FileSaver interface in browsers that do
+not natively support it. There is a [FileSaver.js demo][1] that demonstrates saving
+various media types.
+
+FileSaver.js is the solution to saving files on the client-side, and is perfect for
+webapps that need to generate files, or for saving sensitive information that shouldn't be
+sent to an external server.
+
+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          | [500 MiB][3]  | None         |
+| Chrome for Android | Blob      | Yes          | [500 MiB][3]  | 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) |
+
+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](https://bugs.webkit.org/show_bug.cgi?id=102914) how this bug is affecting you.
+
+Syntax
+------
+
+```js
+FileSaver saveAs(in Blob data, in DOMString filename)
+```
+
+Examples
+--------
+
+### Saving text
+
+```js
+var blob = new Blob(["Hello, world!"], {type: "text/plain;charset=utf-8"});
+saveAs(blob, "hello world.txt");
+```
+
+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"), ctx = canvas.getContext("2d");
+// draw to 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.
