+<para>The formatting plugin allows one to format code easily. The plugin aims to preserve the
+document's undo history and user's cursor position when formatting the code so that the formatting
+of code doesn't disrupt user's work. This is especially important for automatic formatting on save.</para>

+
+<para>The plugin can be configured in two ways:
+<itemizedlist>
+<listitem><para>Globally, from the Configure dialog</para></listitem>
+<listitem><para>On a per project basis using the <filename>.kateproject</filename> file</para></listitem>
+</itemizedlist>
+</para>
+
+<para>When reading the config, the plugin will first try to read the config from <filename>.kateproject</filename> file and then read the global config.
+Example:
+</para>
+
+<screen>
+{
+    "formatOnSave": true,
+    "formatterForJson": "jq",
+    "cmake-format": {
+        "formatOnSave": false
+    },
+    "autopep8": {
+        "formatOnSave": false
+    }
+}
+</screen>
+
+<para>The above:
+<itemizedlist>
+<listitem><para>enables "format on save" globally</para></listitem>
+<listitem><para>specifies "jq" as the formatter for JSON</para></listitem>
+<listitem><para>disables "format on save" for cmake-format and autopep8</para></listitem>
+</itemizedlist>
+</para>
+
+<para>To configure formatting for a project, first create a <filename>.kateproject</filename> file and then add a <code>"formatting"</code> object to it.
+In the <code>"formatting"</code> object you can specify your settings as shown in the previous example. Example:
+</para>
+<note><para>You need to enable the <link linkend="kate-application-plugin-projects">Project plugin</link> for this to work</para></note>
+
