-# Brightness widget
-
-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 |
-| `color` | `beautiful.fg_color` | Color of the arc |
-| `bg_color` | `#ffffff11` | Color of the arc's background |
-| `path_to_icon` | `/usr/share/icons/Arc/status/symbolic/display-brightness-symbolic.svg` | Path to the icon |
-| `timeout` | 1 | How often in seconds the widget refreshes |
-
-### Example:
-
-```lua
-brightnessarc_widget({
- get_brightness_cmd = 'xbacklight -get',
- inc_brightness_cmd = 'xbacklight -inc 5',
- dec_brightness_cmd = 'xbacklight -dec 5'
- color = '/usr/share/icons/Arc/status/symbolic/brightness-display-symbolic.svg'
-})
-```
-
-
-## Installation
-
-First you need to get the current brightness level. There are two options:
-
- - using `xbacklight` command (depending on your video card (I guess) it may or may not work)
-
- To check if it works install xbackligth and check if it works:
-
- ```bash
- sudo apt-get install xbacklight
- xbacklight -get
- ```
-
- If there is no output it means that it doesn't work, but there is a second option:
-
- - using `light` command
-
- Install it from this git repo: [github.com/haikarainen/light](https://github.com/haikarainen/light) and check if it works but running
-
- ```bash
- git clone https://github.com/haikarainen/light.git && \
- cd ./light && \
- sudo make && sudo make install \
- light -G
- 49.18
- ```
-
-Then clone this repo under **~/.config/awesome/**:
-
-```bash
-git clone https://github.com/streetturtle/awesome-wm-widgets.git ~/.config/awesome/awesome-wm-widgets
-```
-
-Require widget at the beginning of **rc.lua**:
-
-```lua
-local brightnessarc_widget = require("awesome-wm-widgets.brightnessarc-widget.brightnessarc")
-```
-
-Add widget to the tasklist:
-
-```lua
-s.mytasklist, -- Middle widget
- { -- Right widgets
- layout = wibox.layout.fixed.horizontal,
- ...
- -- default
- brightnessarc_widget(),
- -- or customized
- brightnessarc_widget({
- get_brightness_cmd = 'xbacklight -get',
- inc_brightness_cmd = 'xbacklight -inc 5',
- dec_brightness_cmd = 'xbacklight -dec 5'
- })
- }
- ...
-```
-
-## Controls
-
-In order to change brightness by shortcuts you can add them to the `globalkeys` table in the **rc.lua**:
-
-```lua
-awful.key({ modkey }, ";", function () awful.spawn("light -A 5") end, {description = "increase brightness", group = "custom"}),
-awful.key({ modkey, "Shift"}, ";", function () awful.spawn("light -U 5") end, {description = "decrease brightness", group = "custom"}),
-```
-On laptop you can use `XF86MonBrightnessUp` and `XF86MonBrightnessDown` keys.
