+Org Mobile is a protocol for synchronizing Org files between Emacs and
+other applications, e.g., on mobile devices.  It enables offline-views
+and capture support for an Org mode system that is rooted on a ``real''
+computer.  The external application can also record changes to
+existing entries.
+
+This appendix describes Org's support for agenda view formats
+compatible with Org Mobile.  It also describes synchronizing changes,
+such as to notes, between the mobile application and the computer.
+
+To change tags and TODO states in the mobile application, first
+customize the variables @code{org-todo-keywords} and @code{org-tag-alist}.
+These should cover all the important tags and TODO keywords, even if
+Org files use only some of them.  Though the mobile application is
+expected to support in-buffer settings, it is required to understand
+TODO states @emph{sets} (see @ref{Per-file keywords}) and
+@emph{mutually exclusive} tags (see @ref{Setting tags}) only for those set in
+these variables.

+
+@vindex org-mobile-directory
+The mobile application needs access to a file directory on
+a server@footnote{For a server to host files, consider using a WebDAV server,
+such as @uref{https://nextcloud.com, Nextcloud}.  Additional help is at this @uref{https://orgmode.org/worg/org-faq.html#mobileorg_webdav, FAQ entry}.} to interact with Emacs.  Pass its location through
+the @code{org-mobile-directory} variable.  If you can mount that directory
+locally just set the variable to point to that directory:
+
+@lisp
+(setq org-mobile-directory "~/orgmobile/")
+@end lisp
+
+@noindent
+Alternatively, by using TRAMP (see @ref{Top,TRAMP User Manual,,tramp,}),
+@code{org-mobile-directory} may point to a remote directory accessible
+through, for example, SSH and SCP:
+
+@lisp
+(setq org-mobile-directory "/scpc:user@@remote.host:org/webdav/")
+@end lisp
+
+@vindex org-mobile-encryption
+With a public server, consider encrypting the files.  Org also
+requires OpenSSL installed on the local computer.  To turn on
+encryption, set the same password in the mobile application and in
+Emacs.  Set the password in the variable
+@code{org-mobile-use-encryption}@footnote{If Emacs is configured for safe storing of passwords, then
+configure the variable @code{org-mobile-encryption-password}; please read
+the docstring of that variable.}.  Note that even after the mobile
+application encrypts the file contents, the file name remains visible
+on the file systems of the local computer, the server, and the mobile
+device.
+
+@node Pushing to the mobile application
+@subsection Pushing to the mobile application
+
+@findex org-mobile-push
+@vindex org-mobile-files
+The command @code{org-mobile-push} copies files listed in
+@code{org-mobile-files} into the staging area.  Files include agenda files
+(as listed in @code{org-agenda-files}).  Customize @code{org-mobile-files} to
+add other files.  File names are staged with paths relative to
+@code{org-directory}, so all files should be inside this directory@footnote{Symbolic links in @code{org-directory} need to have the same name
+as their targets.}.
+
+Push creates a special Org file @samp{agendas.org} with custom agenda views
+defined by the user@footnote{While creating the agendas, Org mode forces ID properties on
+all referenced entries, so that these entries can be uniquely
+identified if Org Mobile flags them for further action.  To avoid
+setting properties configure the variable
+@code{org-mobile-force-id-on-agenda-items} to @code{nil}.  Org mode then relies
+on outline paths, assuming they are unique.}.
+
+Finally, Org writes the file @samp{index.org}, containing links to other
+files.  The mobile application reads this file first from the server
+to determine what other files to download for agendas.  For faster
+downloads, it is expected to only read files whose checksums@footnote{Checksums are stored automatically in the file
+@samp{checksums.dat}.}
+have changed.
+
+@node Pulling from the mobile application
+@subsection Pulling from the mobile application
+
+@findex org-mobile-pull
+The command @code{org-mobile-pull} synchronizes changes with the server.
+More specifically, it first pulls the Org files for viewing.  It then
+appends captured entries and pointers to flagged or changed entries to
+the file @samp{mobileorg.org} on the server.  Org ultimately integrates its
+data in an inbox file format, through the following steps:
+
+@enumerate
+@item
+@vindex org-mobile-inbox-for-pull
+Org moves all entries found in @samp{mobileorg.org}@footnote{The file will be empty after this operation.} and appends
+them to the file pointed to by the variable
+@code{org-mobile-inbox-for-pull}.  It should reside neither in the
+staging area nor on the server.  Each captured entry and each
+editing event is a top-level entry in the inbox file.
+
+@item
+@cindex @samp{FLAGGED}, tag
+After moving the entries, Org processes changes to the shared
+files.  Some of them are applied directly and without user
+interaction.  Examples include changes to tags, TODO state,
+headline and body text.  Entries requiring further action are
+tagged as @samp{FLAGGED}.  Org marks entries with problems with an error
+message in the inbox.  They have to be resolved manually.
+
+@item
+Org generates an agenda view for flagged entries for user
+intervention to clean up.  For notes stored in flagged entries, Org
+displays them in the echo area when point is on the corresponding
+agenda item.
+
+@table @asis
+@item @kbd{?}
+Pressing @kbd{?} displays the entire flagged note in
+another window.  Org also pushes it to the kill ring.  To
+store flagged note as a normal note, use @kbd{? z C-y C-c C-c}.  Pressing @kbd{?} twice does these things: first
+it removes the @samp{FLAGGED} tag; second, it removes the flagged
+note from the property drawer; third, it signals that manual
+editing of the flagged entry is now finished.
+@end table
+@end enumerate
+
+@kindex ? @r{(Agenda dispatcher)}
+From the agenda dispatcher, @kbd{?} returns to the view to finish
+processing flagged entries.  Note that these entries may not be the
+most recent since the mobile application searches files that were last
+pulled.  To get an updated agenda view with changes since the last
+pull, pull again.
