+# Script: info-airqualityindex
+
+A script that shows the local World Air Quality Index. It's an indicator for the air pollution.
+
+![info-airqualityindex](screenshots/1.png)
+
+
+## Dependencies
+
+* `curl`
+* `jq`
+
+
+## Configuration
+
+You need an API token. [Request one](https://aqicn.org/data-platform/token/).
+
+Choose a city and make sure that the result is what you expect. `berlin` is a valid `CITY` here: http://aqicn.org/city/berlin/. Or use the [map](https://aqicn.org/map/) to find a monitoring station near you. `germany/berlin/friedrichshain-frankfurter-allee` works also as `CITY`.
+
+If `CITY` is left empty, the location is retrieved via the Mozilla Location API.
+
+
+## Module
+
+```ini
+[module/info-airqualityindex]
+type = custom/script
+exec = ~/polybar-scripts/info-airqualityindex.sh
+interval = 600
