Noob question about the file browser

Ok, I have been boggling my mind trying to figure out what I am doing wrong here..

I am working with the _samples/api.html
and I cannot figure out how to implement the file uploader thing..
I have read through the documentation and it mentions the code as such

CKEDITOR.replace( 'editor1',
    {
        filebrowserBrowseUrl : '/browser/browse.php',
        filebrowserUploadUrl : '/uploader/upload.php'
    });
