 1 | # bain - the battery indicator
 2 | 
 3 | ![Arch Example](example/Arch.png)
 4 | <sup>\*green: discharge, yellow: charge, red: battery percentage < 30%</sup>
 5 | 
 6 | ## How to use?
 7 | 
 8 | * Make sure you have these programs installed on your machine: [git](https://git-scm.com/), [imagemagick](https://imagemagick.org), and [feh](https://feh.finalrewind.org).
 9 | 
10 | * Clone the repository into `~/.bain`
11 | 
12 | ```bash
13 | git clone https://github.com/amirashabani/bain ~/.bain
14 | ```
15 | 
16 | * Make it executable
17 | 
18 | ```bash
19 | chmod +x ~/.bain/bain
20 | ```
21 | 
22 | * Copy it to `/usr/local/bin`, so that the command is recognized by your terminal. Make sure to run it with `sudo`.
23 | ```bash
24 | sudo cp ~/.bain/bain /usr/local/bin
25 | ```
26 | 
27 | * Run the script from your startup file (e.g. `.xinitrc`). Make sure to use `&` at the end of the command as it is a blocking script.
28 | ```bash
29 | bain arch &
30 | ```
31 | 
32 | * Restart your X session (log out and log back in).
33 | ```bash
34 | pkill X
35 | ```
36 |
