 The *lightline* plugin is a light and configurable statusline for Vim.
 
+------------------------------------------------------------------------------
+SPIRIT						*lightline-spirit*
+
+	Minimalism
+	    The core script is very small.
+
+	Configurability
+	    You can create your own component and easily add to the statusline.
+
+	Orthogonality
+	    Any plugin should not change the settings of another plugin.
+	    Such plugin-crossing settings should be written by users in
+	    .vimrc.
+
+	You might find this plugin is not so useful in default. This plugin
+	does not provide the branch information, which is a very basic
+	component in existing plugins. The reason is: branch component is one
+	of plugin-crossing settings so users should write the settings using
+	the APIs of the both plugins. Hospitality makes a plugin messy. Good
+	APIS keep a plugin clean.
