+# Styles
+
+## Overview
+Styles - set of functions and parameters for components to customize their behavior.
+
+Styles is a table, where key is name of component, and value is style table for this component.
+
+In component API documentation, you can find the style API for this component. Or just lookup for existing styles and modify them.
+
+## Usage
+Setup default druid style for all druid instances via `druid.set_default_style`
+```lua
+local druid = require("druid.druid")
+local my_style = require("my.amazing.style")
+
+local function init(self)
+	druid.set_default_style(my_style)
+end
+```
+
+Setup custom style to specific druid instance:
+```lua
+local druid = require("druid.druid")
+local my_style = require("my.amazing.style")
+
+local function init(self)
+	-- This druid instance will be use my_style as default
+	self.druid = druid.new(self, my_style)
+end
+```
+
+Change component style with _set_style_ function
+```lua
+local druid = require("druid.druid")
+local my_style = require("my.amazing.style")
+
+local function init(self)
+	self.druid = druid.new(self)
+	self.button = self.druid:new_button(self, "node")
+	-- Setup custom style for specific component
+	self.button:set_style(my_style)
+end
+```
+
+## Create custom components
+Styles is just lua table, so it can be described in just one single file
