+= Automatically restore unsaved work after a crash.
+
+When Kakoune crashes, it automatically writes out unsaved changes to backup
+files with predictable names. When you edit a file, if such a backup file
+exists, this plugin will automatically load the content of the backup file
+instead.
+
+By default, backup files are deleted when restored. You can set the
+`autorestore_purge_restored` option to `false` to prevent this.
+
+If you don't want backups to be restored automatically, use the
+`autorestore-disable` command to disable the feature for the current session,
+or put it in your `kakrc` to disable the feature forever.

+= Kakoune's online documentation
+
+This is Kakoune's online documentation system.
+
+To see what documentation topics are available, type `:doc` and look at the
+completion menu.  To view a particular topic, type its name or select it
+from the completion menu.  Then hit Enter.
+
+Documentation will be displayed in the client named in the `docsclient` option.
+
+== Using the documentation browser
+
+Documentation buffers are like any other buffer, so you can scroll through
+them as normal, search within a topic with `/`, etc.  However, they can also
+contain links: <<doc#demonstration-target,like this>>.  Links can be followed
+by moving the cursor onto them and pressing Enter.  If a link takes you to
+a different documentation topic, you can return to the original by using the
+`:buffer` command.
+
+== Writing documentation
+
+Documentation must be in AsciiDoc format, with the extension `.asciidoc`.
+It must be stored somewhere within <<doc#sources,the documentation search
+path>>.  Kakoune's built-in documentation renderer does not necessarily
+support every feature, so don't go overboard with formatting.
+
+To create a link to another documentation topic, the URL should be the topic's
+name, just like `:doc` uses.  Because topics are identified only by their
+basename, you should take care that your topic's name does not conflict with
+any of the names used either by other plugins or by Kakoune's standard library.
+
+== Sources
+
+The `:doc` command searches within the following locations for
+documents in the AsciiDoc format (`*.asciidoc`):
+
+* The user plugin directory, `"%val{config}/autoload"`
+* The system documentation directory, `"%val{runtime}/doc"`
+* The system plugin directory, `"%val{runtime}/rc"`
+
+It searches recursively, and follows symlinks.
+
+== Demonstration target
+
+Well done! You can <<doc#using-the-documentation-browser,go back now>>!

+= Integrate with tools that check files for problems.
+
+Many file-formats have "lint" tools that check for common problems and point out
+where they occur. Most of these tools produce output in the traditional message
+format:
+
+----
+{filename}:{line}:{column}: {kind}: {message}
+----
+
+If the 'kind' field contains 'error', the message is treated as an error,
+otherwise it is assumed to be a warning.
+
+The `:lint-buffer` and `:lint-selections` commands will run the shell command
+specified in the `lintcmd` option, passing it the path to a temporary file
+containing the text to be linted. The results are collected in the
+`*lint-output*` buffer, and analyze it. If `toolsclient` is set, the
+`*lint-output*` buffer will be displayed in the named client.
+
+Each reported error or warning causes a marker to appear in the left-hand
+margin of the buffer that was checked. When the main cursor moves onto that
+line, the associated messages are displayed. If they get distracting, you can
+turn off the markers and messages with the `:lint-hide-diagnostics` command.
+
+You can also use `:lint-next-message` and `:lint-previous-message` to jump
+between the lines with messages.
