-:hammer: Work in progress...:construction:
+
+Almost the same as [volumebar widget](https://github.com/streetturtle/awesome-wm-widgets/tree/master/volumebar-widget), but using arcchart:
+
+![screenshot](out.gif)
+
+Supports:
+ - scroll up - increase volume,
+ - scroll down - decrease volume,
+ - left click - mute/unmute.
+
+## 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,
+		...
+		volumearc_widget,
+		...
+```
