+Poezio plugins
+==============
+
+Starting from the 0.7.5 version, poezio supports plugins.
+Here is a quick howto and a plugin index.
+
+
+Setting up plugins
+------------------
+Poezio seeks the plugins in the _~/.local/share/poezio/plugins/_ dir (more
+generally, the _$XDG_DATA_HOME/poezio/plugins/_ dir), but that can be changed
+by setting the _plugins_dir_ option in the
+link:../configure.html[configuration file] to the directory where you want to
+put your plugins.
+
+
+Plugins autostart
+-----------------
+Use the _plugins_autoload_ option (from the
+link:../configure.html[configuration file]) to select which plugins should be
+loaded on startup. The value is a list of plugin names separated by spaces,
+e.g.
+
+.plugins_autoload example
+---------
+plugins_autoload = "gpg tell exec"
+---------
+
+Plugins configuration
+---------------------
+Most plugins will manage their configuration internally, and you do not (and
+should not) have to edit it, but some (e.g. mpd_client or gpg) require manual
+editing (the _/set_ command can be used, but it is not pleasant to set
+multiple values with it).
+
+The plugin configuration directory is located in _~/.config/poezio/plugins/_
+(or _$XDG_CONFIG_HOME/poezio/plugins/_) and the file related to a specific
+plugin is named _plugin_name.cfg_. The configuration options should usually be
+inside a section named after the plugin (sections are delimited with _[]_).
+
+.section example
+--------------
+[plugin_name]
+key = value
+other_key = other_value
