+Syncthing
+=========
+
+Description
+-----------
+
+The `syncthing` role installs [Syncthing](https://syncthing.net/) and
+configures a dedicated Syncthing instance for each specified user.
+
+Using the exported `syncthing_apache_config` block, users are able to access
+their server GUI by navigating to `https://$HOSTNAME/$USERNAME/` (GSSAPI
+authentication is used).
+
+Note that if you use NFS home directories, you'll need to whitelist the
+Syncthing host for non-Kerberized NFS. Each user's Syncthing instance runs
+under their own UID, and I haven't yet figured out a good way to shuffle
+keytabs around.
+
+
