+# Script: openweathermap-forecast
+
+A weather script that displays a weather forecast.
+
+It shows icons and temperatures for the current weather and the 3 hour forecast.
+
+
+## Dependencies
+
+* [OpenWeatherMap Key](https://openweathermap.org/appid)
+* [weather-icons](https://github.com/erikflowers/weather-icons) or [Font Awesome 5 Pro](https://fontawesome.com/changelog/latest)
+* `jq`
+
+
+## Configuration
+
+If `CITY` is left empty, the location is retrieved via the Mozilla Location API. `CITY` can either be a city ID (e.g. ID of Berlin is `2950159`), city name (e.g. `Berlin`) or city name + country code (e.g. `Berlin,DE`).
+
+Change these values:
+
+```sh
+KEY=""
+CITY=""
+UNITS="metric"
+SYMBOL="°"
+```
+
+
+## Module
+
+```ini
+[bar/polybar]
+...
+font-2 = Weather Icons:size=12;1
+...
+```
+
+```ini
+[module/openweathermap-forecast]
+type = custom/script
+exec = ~/polybar-scripts/openweathermap-forecast.sh
+interval = 600
+label-font = 3
+```
