 This widget represents current brightness level: ![Brightness widget](./br-wid-1.png)
 
+## Customization
+
+It is possible to customize widget by providing a table with all or some of the following config parameters:
+
+| Name | Default | Description |
+|---|---|---|
+| `get_brightness_cmd` | `light -G` | Get current screen brightness |
+| `inc_brightness_cmd` | `light -A 5` | Increase brightness |
+| `dec_brightness_cmd` | `light -U 5`| Decrease brightness |
+| `path_to_icon` | `/usr/share/icons/Arc/status/symbolic/display-brightness-symbolic.svg` | Path to the icon |
+| `font` | `Play 9` | Font |
+
+### Example:
+
+```lua
+brightness_widget({
+    get_brightness_cmd = 'xbacklight -get',
+    inc_brightness_cmd = 'xbacklight -inc 5',
+    dec_brightness_cmd = 'xbacklight -dec 5'

+    ```
+
+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.
