+## Customization
  
+It is possible to customize widget by providing a table with all or some of the following config parameters:
+
+| Name | Default | Description |
+|---|---|---|
+| `main_color` | `beautiful.fg_normal` | Color of the bar |
+| `mute_color` | `beautiful.fg_urgent` | Color of the bar when mute |
+| `width` | 50 | The bar width |
+| `shape` | `bar` | [gears.shape](https://awesomewm.org/doc/api/libraries/gears.shape.html), could be `octogon`, `hexagon`, `powerline`, etc |
+| `margin` | `10` | Top and bottom margin (if your wibar is 22 px high, bar will be 2 px (22 - 2*10)) |
+| `get_volume_cmd` | `amixer -D pulse sget Master` | Get current volume level |
+| `inc_volume_cmd` | `amixer -D pulse sset Master 5%+` | Increase volume level |
+| `dec_volume_cmd` | `amixer -D pulse sset Master 5%-` | Descrease volume level |
+| `tog_volume_cmd` | `amixer -D pulse sset Master toggle` | Mute / unmute |
+
+### Example:
+
  ```lua
-local volumebar_widget = require("awesome-wm-widgets.volumebar-widget.volumebar")
-...
-s.mytasklist, -- Middle widget
-	{ -- Right widgets
-    	layout = wibox.layout.fixed.horizontal,
-		...
-		volumebar_widget,
-		...      
+ volumebar_widget({
+    main_color = '#af13f7',
+    mute_color = '#ff0000',
+    width = 80,
+    shape = 'rounded_bar',
+    margins = 8
+})
  ```
 
+Above config results in following widget:

+
+
+## Installation
+ 
+1. Clone this repo under **~/.config/awesome/**
+
+    ```bash
+    git clone https://github.com/streetturtle/awesome-wm-widgets.git ~/.config/awesome/
+    ```
+
+1. Require volumebar widget at the beginning of **rc.lua**:
+
+    ```lua
+    local volumebar_widget = require("awesome-wm-widgets.volumebar-widget.volumebar")
+    ```
+
+1. Add widget to the tasklist:
+
+    ```lua
+    s.mytasklist, -- Middle widget
+        { -- Right widgets
+            layout = wibox.layout.fixed.horizontal,
+            ...
+            --[[default]]
+            volumebar_widget(),
+            --[[or customized]]
+            volumebar_widget({
+                main_color = '#af13f7',
+                mute_color = '#ff0000',
+                width = 80,
+                shape = 'rounded_bar', -- octogon, hexagon, powerline, etc
+                -- bar's height = wibar's height minus 2x margins
+                margins = 8
+            }),
+
+            ...
+    ```
+
 ## Troubleshooting
 
 If the bar is not showing up, try to decrease top or bottom margin - widget uses hardcoded margins for vertical alignment, so if your wibox is too small then bar is simply hidden by the margins.
