 # Usage
 
-The extension button appears only when browsing a specific domain (*TODO: and only when a single email is displayed*). The extension will help you download all email attachments to a single directory. Also, it will automatically suggest filenames that are prefixed with the current date.
+The extension button appears only when browsing a specific domain, and only when a single email is displayed. The extension will download all attachments into the same directory and prefix their filenames with the current date.
 
-When you click the button, a "Save as …" dialog appears for the first file attached to the email (if there are no attachments, nothing happens). The suggested filename is the original filename prefixed with the current date (`yyyymmdd`, single space, original filename). Choose the directory where you want to save the file and click "Save" to start the download.
-
-After the download has started", a new "Save as …" dialog appears for each remaining attachment (if the email has only one attachment, nothing happens). Each dialog will start in the directory you picked for your first file, and each suggested filename will be prefixed in the same way. Assuming that you want to save all attached files to the same directory, all you need to do is click "Save" for each dialog.   
-
-That's it.
+Click the button to open a file dialog. Here you can choose the directory you want all attachments to be downloaded into. Click OK. That's it.
