    @@ -315,3 +315,231 @@ If you are upgrading to a new (1.0.0 or newer) version of File,
and you have pre
         cdvfile://localhost/persistent/path/to/file
     
     which can be used in place of the absolute file path in both `download()` and `upload()`
methods.
    +
    +## Sample: Download and Upload Files <a name="sample"></a>
    +
    +Use the File-Transfer plugin to upload and download files. In these examples, we demonstrate
several tasks like:
    +
    +* Downloading a binary file to the application cache
    +* Uploading a file created in your application's root
    +* Downloading the uploaded file
    +
    +## Download a Binary File to the application cache
    +
    +Use the File plugin with the File-Transfer plugin to provide a target for the files that
you download (the target must be a FileEntry object). Before you download the file, create
a DirectoryEntry object by using `resolveLocalFileSystemURL` and calling `fs.root` in the
success callback. Use the `getFile` method of DirectoryEntry to create the target file.
    +
    +```js
    +window.requestFileSystem(window.TEMPORARY, 5 * 1024 * 1024, function (fs) {
    +
    +    console.log('file system open: ' + fs.name);
    +
    +    // Make sure you add the domain name to the Content-Security-Policy <meta>
element.
    +    var url = 'http://cordova.apache.org/static/img/cordova_bot.png';
    +    fs.root.getFile('downloaded-image.png', { create: true, exclusive: false }, function
(fileEntry) {
    +        download(fileEntry, url, true);
    +
    +    }, onErrorCreateFile);
    +
    +}, onErrorLoadFs);
    +```
    +
    +>*Note* For persistent storage, pass LocalFileSystem.PERSISTENT to requestFileSystem.

    Consider adding a note explaining the 'exclusive' and 'create' options for the getFile
function.
