+
+The Gnus Cloud is a way to synchronize marks and general files and
+data across multiple machines.
+
+Very often, you want all your marks (what articles you've read, which
+ones were important, and so on) to be synchronized between several
+machines. With IMAP, that's built into the protocol, so you can read
+nnimap groups from many machines and they are automatically
+synchronized. But NNTP, nnrss, and many other backends do not store
+marks, so you have to do it locally.
+
+The Gnus Cloud package stores the marks, plus any files you choose, on
+an IMAP server in a special folder. It's like a
+DropTorrentSyncBoxOakTree(TM).

+@subsection Gnus Cloud Setup
+
+Setting up the Gnus Cloud takes less than a minute. From the Group
+buffer:
+
+Press @kbd{^} to go to the Server buffer. Here you'll see all the
+servers that Gnus knows. @xref{Server Buffer}.
+
+Then press @kbd{i} to mark any servers as cloud-synchronized (their marks are synchronized).
+
+Then press @kbd{I} to mark a single server as the cloud host (it must
+be an IMAP server, and will host a special IMAP folder with all the
+synchronization data). This will set the variable
+@code{gnus-cloud-method} (using the Customize facilities), then ask
+you to optionally upload your first CloudSynchronizationDataPack(TM).
+
+@node Gnus Cloud Usage
+@subsection Gnus Cloud Usage
+
+After setting up, you can use these shortcuts from the Group buffer:
+
+@table @kbd
+@item ~ RET
+@item ~ d
+@findex gnus-cloud-download-all-data
+@cindex cloud, download
+Download the latest Gnus Cloud data.
+
+@item ~ u
+@item ~ ~
+@findex gnus-cloud-upload-all-data
+@cindex cloud, download
+Upload the local Gnus Cloud data. Creates a new
+CloudSynchronizationDataPack(TM).
+
+@end table
+
+But wait, there's more. Of course there's more. So much more. You can
+customize all of the following.
+
+@defvar gnus-cloud-synced-files
+These are the files that will be part of every
+CloudSynchronizationDataPack(TM). They are included in every upload,
+so don't synchronize a lot of large files. Files under 100Kb are best.
+@end defvar
+
+@defvar gnus-cloud-storage-method
+This is a choice from several storage methods. It's highly recommended
+to use the EPG facilities. It will be automatic if have GnuPG
+installed and EPG loaded. Otherwise, you could use Base64+gzip,
+Base64, or no encoding.
+@end defvar
+
+@defvar gnus-cloud-interactive
+When this is set, and by default it is, the Gnus Cloud package will
+ask you for confirmation here and there. Leave it on until you're
+comfortable with the package.
+@end defvar
+
+
+@defvar gnus-cloud-method
+The name of the IMAP server to store the
+CloudSynchronizationDataPack(TM)s. It's easiest to set this from the
+Server buffer (@pxref{Gnus Cloud Setup}).
