## 🧪 How to use the project

To start, you need to create a configuration file in YAML format. This file consists of two keys: `default` to define the path of the default wallpaper, and `workspaces` which allows you to associate each workspace with its corresponding wallpaper.

```yaml
default: /home/alice/wallpapers/default.jpg
workspaces:
  "Name of the workspace 1": /home/alice/wallpapers/1.jpg
  "Name of the workspace 2": /home/alice/wallpapers/2.jpg
  "Name of the workspace 3": /home/alice/wallpapers/3.jpg
```

Next, you simply need to run `i3-wallpaper-manager` while specify the path to the configuration file.

```bash
DISPLAY=:0 i3-wallpaper-manager /path/to/config.yaml
```

To run it when i3 starts, add this to your i3 configuration:

```bash
exec_always DISPLAY=:0 i3-wallpaper-manager /path/to/config.yaml
```
