 # Batteryarc widget
-:hammer: Work in progress...:construction:
+
+This widget is more informative version of [battery widget](https://github.com/streetturtle/awesome-wm-widgets/tree/master/battery-widget).
+
+Depending of the battery status it could look following ways:
+
+ - ![10_d](./10_d.png) - less than 15 percent
+ - ![10_c](./10_c.png) - less than 15 percent, charging
+ - ![20_d](./20_d.png) - between 15 and 40 percent
+ - ![20_c](./20_c.png) - between 15 and 40 percent, charging
+ - ![80_d](./80_d.png) - more than 40 percent
+ - ![80_c](./80_c.png) - more than 40 percent, charging
+
+Widget uses following beautiful variables with values:
+
+```lua
+theme.widget_main_color = "#74aeab"
+theme.widget_red = "#e53935"
+theme.widget_yelow = "#c0ca33"
+theme.widget_green = "#43a047"
+theme.widget_black = "#000000"
+theme.widget_transparent = "#00000000"
+```
+
+which means that you need to copy the code above and paste it in your **theme.lua**. Otherwise you can change colors directly in the widget.
+
+## Installation
+
+Clone repo, include widget and use it in **rc.lua**:
+
+```lua
+require("volumearc")
+...
+s.mytasklist, -- Middle widget
+	{ -- Right widgets
+    	layout = wibox.layout.fixed.horizontal,
+		...
+		batteryarc_widget,
+		...
+```
+
+## Troubleshooting
+
+In case of any doubts or questions don't hesitate to raise an [issue](https://github.com/streetturtle/awesome-wm-widgets/issues/new).
