+Selective Sync
+==============
+
+This is for when you don't want to synchronize *all* files from the cluster
+onto your device, or you want only some directories of your to be synced
+*to* the cluster. There are two mechanisms that support this usage; *Directory
+Selection* and *Excluded Files*.
+
+Directory Selection
+-------------------
+
+By default, all directories in a given folder are synchronized. Using
+directory selection, the synchronization can be limited to a subset of
+directories. The selection is done by using a tree browser. The tree
+represents the cluster wide contents of a folder. The default is represented
+by the top level being checked and directories underneath the top level thus
+being implicitly included::
+
+  [X] ~/Sync
+      [ ] Documents
+          [ ] Processes
+          [ ] Standards
+      [ ] Pictures
+          [ ] Vacation
+          [ ] Work
+      [ ] Music
+          [ ] Classical
+          [ ] Rock
+
+To only synchronize documents and vacation pictures, the following selection can be made::
+
+  [/] ~/Sync
+      [X] Documents
+          [ ] Processes
+          [ ] Standards
+      [ ] Pictures
+          [X] Vacation
+          [ ] Work
+      [ ] Music
+          [ ] Classical
+          [ ] Rock
+
+The top level shows a partial checkbox to indicate that selections have been
+made at a lower level. With this configuration Syncthing will ignore any files
+and directories no in ~/Sync/Documents or ~/Sync/Pictures/Vacation -- no
+changes will be downloaded from the cluster and local changes will not be
+tracked.
+
+.. note:: When displaying the tree we must merge what we actually have on disk with what is in the global state... Or we will not be able to show new directories to the user as we don't know about them...
+
+Excluded Files
+--------------
+
+In addition to using directory selection, specific files can be excluded by
+adding patterns to match them. Excluded files are:
+
+- Ignored when found on disk (i.e. not hashed and not announced to other
+  devices).
+
+- Ignored when announced by other devices (i.e. will not contribute to an "out
+  of sync" status or be fetched from the network).
+
+- *Removed* when present in a directory that is marked for deletion by another
+  *device.
+
+Patterns are in "glob" form, with the following allowed syntax elements:
+
+Asterisk (``*``)
+	Matches zero or more characters.
+
+Question mark (``?``)
+	Matches exactly one character.
+
+Ranges (``[a-f]``)
+	Matches any of the characters in the range exactly once.
+
+Examples:
+
+``*.jpg``
+	Matches all files with the ``jpg`` extension.
+
+``[0-9]*``
+	Matches all files with names starting with a digit.
+
+File exclusions apply only to files, not to directories, and apply equally in
+all directories in the folder.
