 Introduction
 ============
 
-The Magic Folder frontend allows an upload to a Tahoe-LAFS grid to be triggered
-automatically whenever a file is created or changed in a specific local
-directory. It currently works on Linux and Windows.
+The Magic Folder frontend synchronizes local directories on two or more
+clients, using a Tahoe-LAFS grid for storage. Whenever a file is created
+or changed under the local directory of one of the clients, the change is
+propagated to the grid and then to the other clients.
 
-The implementation was written as a prototype at the First International
-Tahoe-LAFS Summit in June 2011, and is not currently in as mature a state as
-the other frontends (web, CLI, SFTP and FTP). This means that you probably
-should not rely on all changes to files in the local directory to result in
-successful uploads. There might be (and have been) incompatible changes to
-how the feature is configured.
+The implementation of the "drop-upload" frontend, on which Magic Folder is
+based, was written as a prototype at the First International Tahoe-LAFS
+Summit in June 2011. In 2015, with the support of a grant from the
+`Open Technology Fund`_, it was redesigned and extended to support
+synchronization between clients. It currently works on Linux and Windows.

 We are very interested in feedback on how well this feature works for you, and
 suggestions to improve its usability, functionality, and reliability.
