Note that widget uses the Arc icon theme, so it should be [installed](https://github.com/horst3180/arc-icon-theme#installation) first under **/usr/share/icons/Arc/** folder.
+## Customization
+
+It is possible to customize widget by providing a table with all or some of the following config parameters:
+
+| Name | Default | Description |
+|---|---|---|
+| `font` | `Play 9` | Font |
+| `city` | `Montreal,ca` | City name and country code, [more info](https://openweathermap.org/current) |
+| `api_key` | none| API key, required |
+| `units` | `metric` | `metric` for celsius, `imperial` for fahrenheit |
+| `both_units_widget` | `false` | show temperature in both units (15°C (59°F)) or in one (15°C) |
+| `both_units_popup` | `false` | same as above but for popup |
+
+### Example:
+
+```lua
+weather_widget({
+ api_key = 'your-api-key',
+ units = 'imperial',
+ font = 'Ubuntu Mono 9'
+}),
+```
+
+
## Installation
1. Install lua socket - to make HTTP calls to get the weather information.
