+The `gios` integration uses the [GIOŚ](http://powietrze.gios.gov.pl/pjp/current) web service as a source for air quality data for your location.
+
+## Setup
+
+To obtain `station_id` of the measuring station, go to [GIOŚ](http://powietrze.gios.gov.pl/pjp/current) page, select the measuring station on the map and click the "More Info" link. The address of the opened page will look like this: `http://powietrze.gios.gov.pl/pjp/current/station_details/chart/291` and `291` will be `station_id` of measuring station.
+
+## Configuration
+
+To add GIOŚ to your installation, go to **Configuration** >> **Integrations** in the UI and enable the GIOŚ integration.
