+## Data Types
+
+The basic types providing locale data in the C++ API are also
+available in QML as `Q_GADGET`s and offer the same properties
+in QML:
+
+\li KCountry
+\li KCountrySubdivision
+
+<a name="country_lookup">
+
+## Country Lookup
+
+The static country lookup methods found in `KCountry` in the C++ API
+are available from the `Country` singleton in QML, as part of the `org.kde.i18n.localeData` module.
+
+### Listing all
+
+For listing all known countries there is the `Country.allCountries` property,
+providing a list of `KCountry` objects.
+
+~~~
+import org.kde.i18n.localeData 1.0
+
+... {
+    ComboBox {
+        model: Country.allCountries
+        displayText: currentValue.emojiFlag + " " + currentValue.name
+    }
+}
+~~~
+
+### Lookup by code, name or location
+
+The following methods allow to obtain a `KCountry` object:
+
+\li `Country.fromAlpha2`
+\li `Country.fromAlpha3`
+\li `Country.fromName`
+\li `Country.fromLocation`
+
+See the corresponding C++ API with the same name in `KCountry` for further details.
+
+
+<a name="subdiv_lookup">
+
+## Country Subdivision Lookup
+
+The static country subdivision lookup methods found in `KCountrySubdivision` in the C++ API
+are available from the `CountrySubdivision` singleton in QML, as part of the `org.kde.i18n.localeData` module.
+
+The following methods allow to obtain a `KCountrySubdivision` object:
+
+\li `CountrySubdivision.fromCode`
+\li `CountrySubdivision.fromLocation`
+
+See the corresponding C++ API with the same name in `KCountrySubdivision` for further details.
+
+
+<a name="timezone_lookup">
+
+## Timezone Lookup
+
+The static country timezone lookup methods found in `KTimeZone` in the C++ API
+are available from the `TimeZone` singleton in QML, as part of the `org.kde.i18n.localeData` module.
+
+The following methods are provided:
+
+\li `TimeZone.country`
+\li `TimeZone.fromLocation`
+
+See the corresponding C++ API with the same name in `KTimeZone` for further details.
+
+
+<a name="refs">
+
+## Further References
+
+There's a standalone QML example showing most of the above mentioned functionality in `tests/demo.qml`
+provided as part of the KI18n source code.
