+FileSaver.js
+============
+
+FileSaver.js implements the HTML5 W3C `saveAs()` [FileSaver][1] interface in browsers that do
+not natively support it. There is a [FileSaver.js demo][2] 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](https://github.com/eligrey/canvas-toBlob.js) for a cross-browser implementation.
+
+Supported Browsers
+------------------
+
+| Browser        | Constructs as | Filenames    | Max Blob Size | Dependencies |
+| -------------- | ------------- | ------------ | ------------- | ------------ |
+| Firefox 20+    | Blob          | Yes          | 800MiB        | None         |
+| Firefox ≤ 19   | data: URI     | No           | n/a           | [Blob.js](https://github.com/eligrey/Blob.js) |
+| Chrome         | Blob          | Yes          | 345MiB        | None         |
+| Chrome for Android | Blob      | Yes          | ?             | None         |
+| IE 10+         | Blob          | Yes          | 600MiB        | None         |
+| Opera Next     | Blob          | Yes          | ?             | 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:
+
+    try { var isFileSaverSupported = !!new Blob(); } catch(e){}
+
+Syntax
+------
+
+    FileSaver saveAs(in Blob data, in DOMString filename)
+
+Examples
+--------
+
+### Saving text
+
+    var blob = new Blob(["Hello, world!"], {type: "text/plain;charset=utf-8"});
+    saveAs(blob, "hello world.txt");
+
+The standard W3C File API [`Blob`][3] interface is not available in all browsers.
+[Blob.js][4] is a cross-browser `Blob` implementation that solves this.
+
+### Saving a canvas
+
+    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][5] is a cross-browser `canvas.toBlob()` that polyfills this.
+
+### Aborting a save
+
+    var filesaver = saveAs(blob, "whatever");
+    cancel_button.addEventListener("click", function() {
+        if (filesaver.abort) {
+            filesaver.abort();
+        }
+    }, false);
+
+This isn't that useful unless you're saving very large files (e.g. generated video).
